Description

The TLE8366 is a PWM step-down DC/DC converter with an integrated 1.8 A power switch, packaged in a small

PG-DSO-8 with exposed pad. There are three versions available, two fixed voltage with 5.0 V (TLE8366EV50) or

3.3 V (TLE8366EV33) and a variable voltage variant named TLE8366EV with a reference feedback voltage of only

600 mV. The wide input voltage range from 4.75 to 45 V makes the TLE8366 suitable for a wide variety of

applications. The device is designed to be used under harsh automotive environment.

The switching frequency of nominal 370 kHz allows the use of small and cost-effective inductors and capacitors,

resulting in a low, predictable output ripple and in minimized consumption of board space. (If desired the device

could be synchronized to an external frequency source between 200 and 530 kHz.)

The TLE8366 includes safety features such as a cycle-by-cycle current limitation, over-temperature shutdown and

input under voltage lockout. The enable function, in shutdown mode with less than 2 µA current consumption,

enables easy power management in battery-powered systems.

The voltage regulation loop provides an excellent line and load regulation. The stability of the loop could be

adjusted by using an external compensation network. This compensation network combined with voltage mode

regulation and a feed-forward control path guarantees a highly effective line transient rejection. During start-up the

integrated soft-start limits the inrush current peak and prevents from a voltage overshoot.

Buck Regulator

Buck Regulator

5.1

Description

5.1.1

Arrangement

The step-down (or buck) regulator consists of several functional blocks, which shall be explained in the following:

The oscillator, the regulator, the safety functions, the gate driver and the internal MOSFET.

5.1.1.1

Regulator Block

The oscillator creates a saw-tooth signal, which is supplied to the PWM comparator and the Schmitt-Trigger 1. The

frequency of the oscillator might be synchronized to an external frequency connected to pin sync.

The Error Amplifier compares the feedback signal to the reference voltage. At the variable voltage version the

feedback pin shall be connected to an external resistor divider, the fixed voltage versions contain an internal

resistor divider. The soft start function is included by the ramp generator between the reference voltage source

and the error amplifier. It generates a defined ramp after the initialization of the device. (The device is initialized

after signal EN turns to high (with supply voltage at VS present) or with rising Supply voltage (with EN = H

connected to VS) or at restarting after a thermal shutdown. The ramp starts, if the Buck Driver Supply (BDS)

external capacitor is charged.

Only for the variable voltage version: If the feedback signal at pin FB gets lost, an internal pull-up current source

will pull the pin too high thus preventing the output voltage from overshooting.

A compensation network needs to be connected to the output of the error amplifier using pin COMP.

The PWM comparator creates the Pulse-Width Modulated (PWM) signal by comparing the error amplifier output

with the saw-tooth signal from the oscillator.

5.1.1.2

Safety Functions Block

The safety functions block consists of the Error-Flip Flop, the Nor1 Gate and the PWM-Flip-Flop.

The Error Flip-Flop collects the failure events such as the over-current shutdown of the internal MOSFET, the

output overvoltage shutdown and the temperature shutdown.

The over-current shutdown signal is created by the OC comparator. It detects the voltage across an internal shunt

resistor. If the current exceeds the reference level, the pulse is shut down and the MOSFET switched off.

The bootstrap under-voltage shutdown is created by the BDS UV comparator, which compares the bootstrap

capacitor voltage to a reference level. If the bootstrap capacitor voltage is too low, the pulse will be shut down and

the MOSFET switched off.

If the output voltage exceeds a reference value, the pulse will also be shut down and the MOSFET switched off.

Data sheet

7

Rev. 1.0, 2009-05-18

TLE8366

Buck Regulator

An internal temperature sensor detects the temperature of the device, it will be switched off if the junction

temperature exceeds 175 °C.

The error Flip flop is set by the Schmitt Trigger 1 and will be reset by one of these signals. This will close the NOR1

gate and shutdown the pulse. The bootstrap capacitor monitoring is connected directly to the NOR1 gate.

The bootstrap under-voltage shutdown is created by the BDS UV comparator, which compares the bootstrap

capacitor voltage to a reference level. If the bootstrap capacitor voltage is too low, the pulse will be shut down.

PWM pulses are passing through the NOR 1 gate. In case if one of the mentioned failures will occur this gate will

be closed and the pulse switched immediately off.

The PWM Flip-Flop is set by NAND2, which combines the clock from the Schmitt Trigger 1 with the output from

NOR1. The PWM Flip-Flop is reset by the output of the NOR1.

5.1.1.3

Internal Power Stage

The gate driver consists of the Gate driver itself, an inverter for the PWM signal and the gate driver supply. The

gate Driver Supply is connected over pin BDS to the BDS capacitor. A charge pump is integrated to support the

gate drive in cases of low input voltage, small differential voltage between input supply and output voltage and

during start up. To minimize emissions the charge pump is switched off if the input voltage is high enough to charge

the bootstrap capacitor.

5.1.2

Operation Mode

The PWM pulses are voltage controlled. The error amplifier and the PWM comparator are creating the PWM

pulses using the oscillator saw-tooth signal and the feedback voltage. The pulse-width modulation is done so that

the feedback voltage (at pin FB for the adjustable version) is similar to the reference voltage (0.6 V).

Between input voltages from 8.0 to 36 V the integrated feed forward path provides a fast line transient rejection.

(feed-forward means sensing the input voltage and react on fluctuations before they influence the output)

To achieve a stable output voltage even under low duty cycle conditions (light load down to zero output load and/or

high input voltage) a pulse skipping mode is implemented. Pulse skipping is also used for operation with low supply

voltages leading to duty cycles > 92%.

Module Enable and Thermal Shutdown

6.1

Description

With the enable pin the device can be set in off-state reducing the current consumption to less than 2µA.

The enable function features an integrated pull down resistor which ensures that the IC is shut down and the power

switch is off in case the pin EN is left open.

The integrated thermal shutdown function turns the power switch off in case of overtemperature. The typ. junction

shutdown temperature is 175°C, with a min. of 160°C. After cooling down the IC will automatically restart

operation. The thermal shutdown is an integrated protection function designed to prevent IC destruction when

operating under fault conditions. It should not be used for normal operation.

Module Oscillator

7.1

Description

The oscillator supplies the device with a constant frequency. The power switch will be switched on and off with a

constant frequency. The duty-cycle is derived from this frequency and some safety functions are synchronized to

this frequency.

The internal sawtooth signal used for the PWM generation has an amplitude proportional to the input supply

voltage (feedforward).

The turn-on frequency can optionally be set externally via the ’SYNC’ pin. In this case the synchronization of the

PWM-on signal refers to the falling edge of the ’SYNC’-pin input signal. In case the synchronization to an external

clock signal is not needed the ’SYNC’ pin should be connected to GND.

Leaving pin SYNC open or short-circuiting it to GND leads to normal operation with the internal switching

frequency.

Application Information

Note:The following information is given as a hint for the implementation of the device only and shall not be

regarded as a description or warranty of a certain functionality, condition or quality of the device.

8.1

Frequency Compensation

The stability of the output voltage can be achieved with a simple RC connected between pin COMP and GND. The

standard configuration using the swiching frequency of the internal oscillator is a ceramic capacitor C_COMP= 22nF

and R_COMP= 22kΩ. By slight modifications to the compensation network the stability can be optimized for different

application needs, such as varying switching frequency (using the sychronizing function), different types of buck

capacitor (ceramic or tantalum) etc.

The compensation network is essential for control loop stability. Leaving pin COMP open might lead to instable

operation.

8.2

Compensating a tantalum buck capacitor C_BU1

The control loop is optimized for use of ceramic buck capacitors C_BU. In order to maintain stability also for tantalum

capacitors with ESR up to 300mΩ, an additional compensation capacitance C_COMP2at pin COMP to GND is

required. It’s value calculates:

C_COMP2= C_BU* ESR(C_BU) / R_COMP,

whereas C_COMP2needs to stay below 5nF.

Application Diagram TLE8366EV

Note:This is a very simplified example of an application circuit. The function must be verified in the real application

The output voltage of the TLE8366EV can be programmed by a voltage divider connected to the feedback pin FB.

The divider cross current should be 300 µA at minimum, therefore the maximum R₂calculates:

R₂≤ V_FB/ I_R2--> R₂≤ 0.6V / 300 µA = 2 kΩ

For the desired output voltage level V_CC, R₁calculates then (neglecting the small FB input current):
