Description

PT6520

These power modules are a series of

high performance, 8-A rated, Integrated

Switching Regulators (ISRs), housed in a

low cost 14-Pin SIP (Single In-line Pack-

age). Operating from either a 3.3V or 5V

standard power bus, the PT6520 series

produces a high-output, low-voltage

power source for the industry’s latest

high-speed, microprocessors, ASICs, &

DSPs. This allows for the easy integration

of these new low-voltage ICs into existing

3.3V or 5V systems without re-designing

the power supply.

Notes: (1) The ISR will operate at no load with reduced specifications.

(2) The STBY* control (pin 3) has an internal pull-up and if it is left open circuit the module will operate when input power is applied. The open-circuit

voltage is typically 12.6V, and maybe as high as 15V. Refer to the application notes for other interface considerations.

(3) See Safe Operating Area curves or contact the factory for the appropriate derating.

(4) The tab pins on the 16-pin mount package types (suffixes L & M) must be soldered. For more information see the applicable package outline drawing.

Input/Output Capacitors: The PT6520 series requires a 330µF capacitor at both the input and output for proper operation in all applications. In addition, the input

capacitance (C_in) must be rated for a minimum of 1.2Arms ripple current rating. For transient or dynamic load applications, additional output capacitance (C_out) may be

necessary. The maximum allowable output capacitance is 5,000µF. For more information consult the related application note on capacitor recommendations.

PT6520 Series

Using the Standby Function of the PT6520

Series of Integrated Switching Regulators

Figure 1

The PT6520 series of power modules are high efficiency

regulators that operate off either a 3.3V or 5V input

bus voltage. These regulators incorporate a Standby

function, which may be used in applications that require

power-up/shutdown sequencing, and wherever there is a

requirement for the output status of the module to be

controlled by external circuitry.

The standby function is provided by the STBY* control,

pin 3. If pin 3 is left open-circuit the regulator operates

normally, and provides a regulated output when a valid

supply voltage is applied to V_in(pins 4–6) with respect

to GND (pins 7–10). If a low voltage is then applied

Q1

BSS138

Inhibit

to pin 3 the regulator output will be disabled and the

input current drawn by the ISR will be reduced to about

3

15mA . The standby control may also be used to hold-off

the regulator output during the period that input power is

applied.

Turn-On Time: In the circuit of Figure 1, turning Q₁on applies

a low voltage to the STBY control (pin 3) and disables the

regulator ouput. Correspondingly, turning Q₁off removes the

low-voltage signal and enables the output. Once enabled, the

output will typically experience a 10–15ms delay followed by a

predictable ramp-up of voltage. The regulator should provide a

fully regulated output voltage within 40ms. The waveform of

Figure 2 shows the output voltage and input current waveforms

of a PT6521 (3.3V) following the turn-off of Q₁. The turn off

of Q₁corresponds to the rise in Vstby. The waveforms were

measured with a 5Vdc input voltage, and 4.5A resistive load.

Pin 3 is ideally controlled with an open-collector (or open-

drain) discrete transistor (See Figure 1). The open-circuit

voltage is typcially 12.6V. Table 1 gives the circuit pa-

rameters for this control input.

2. The standby control input is Not compatible with TTL or

other devices that incorporate a totem-pole output drive.

Use only a true open-collector device, preferably a discrete

bipolar transistor (or MOSFET). To ensure the regulator

output is disabled, the control pin must be pulled to less

than 0.4Vdc with a low-level 0.5mA sink to ground.

Notes:

location. Place the resistor as close to the ISR as

possible.

Refer to Figure 1 and Table 2 for both the placement and value

of the required resistor, either (R₁) or R₂as appropriate.

The values of (R1) [adjust down], and R2 [adjust up], can

also be calculated using the following formulas.

2. Never connect capacitors from V_oadjust to either

GND, V_out, or the Remote Sense pin. Capacitance

added to the V_oadjust pin will affect the stability of

the ISR.

PT6520 Series

Tantalum Capacitors

Capacitor Recommendations for the PT6520 Series of

Integrated Switching Regulators

Tantalum type capacitors may be used for the output but

only the AVX TPS series, Sprague 593D/594/595 series

or Kemet T495/T510 series. These capacitors are rec-

ommended over many other tantalum types due to their

higher rated surge, power dissipation, and ripple current

capability. As a caution the TAJ series by AVX is not

recommended. This series has considerably higher ESR,

reduced power dissipation, and lower ripple current

capability. The TAJ series is less reliable than the AVX

TPS series when determining power dissipation capability.

Tantalum or Oscon® types are recommended for appli-

cations where ambient temperatures fall below 0°C.

Input Capacitors:

The recommended input capacitance is determined by

1.0 ampere minimum ripple current rating and 330µF

minimum capacitance (300µF for Oscon® or low ESR

tantalum). Ripple current and <100mΩ equivalent series

resistance (ESR) values are the major considerations,

along with temperature, when designing with different

types of capacitors. Tantalum capacitors have a recom-

mended minimum voltage rating of 2× the maximum

DC voltage + AC ripple. This is necessary to insure

reliability for input voltage bus applications

Capacitor Table

Table 1 identifies the characteristics of capacitors from a

number of vendors with acceptable ESR and ripple cur-

rent (rms) ratings. The number of capacitors required at

both the input and output buses is identified for each

capacitor type.

Output Capacitors:

The ESR of the required capacitor (C_out) must not be

greater than 150mΩ. Electrolytic capacitors have poor

ripple performance at frequencies greater than 400kHz

but excellent low frequency transient response. Above

the ripple frequency, ceramic capacitors are necessary to

improve the transient response and reduce any high

frequency noise components apparent during higher

current excursions. Preferred low ESR type capacitor

part numbers are identified in Table 1.

This is not an extensive capacitor list. Capacitors from other

vendors are available with comparable specifications. Those listed

are for guidance. The RMS ripple current rating and ESR

(Equivalent Series Resistance at 100kHz) are critical parameters

necessary to insure both optimum regulator performance and

long capacitor life.

⁽¹⁾The marketing status values are defined as follows:

ACTIVE: Product device recommended for new designs.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.

NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in

Eco Plan

-

The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS

&

no Sb/Br)

-

please check

http://www.ti.com/productcontent for the latest availability information and additional product content details.

TBD: The Pb-Free/Green conversion plan has not been defined.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements

for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered

at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame

retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)

(3)

MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder

temperature.
