The PT6340 Excalibur™ power modules
are a series of high performance Integrated
Switching Regulators (ISRs), housed in a
thermally efficient solderable copper case.
These modules operate from a 12V input
voltage bus to produce a high-output low-
voltage power source; ideal for powering the
industry’s latest DSP and microprocessors.
The series includes standard output bus
voltages ranging from 5VDC to 1.2VDC.
The innovative copper case construction
provides superior thermal performance in a
small footprint. Both through-hole and
surface mount pin configurations are avail-
able. The PT6340 series operating features
include external output voltage adjustment,
an On/Off inhibit, and short-circuit protection.
A 100µF input, and 330µF output capacitor
are required for proper operation.

Notes: (1) The ISR will operate at no load with reduced specifications.
(2) The Inhibit control (pin 1) has an internal pull-up and if it is left open circuit the module will operate when input poweris applied. The open-circuit
voltage is the input voltage Vin. Use a discrete MOSFET to control the Inhibit pin, and ensure a transitioin time of less than ≤10µs. Consult the related
application note for other interface considerations.
(3) For operation below 0°C, Cin and Cout must have stable characteristics. Use either low ESR tantalum or Oscon® capacitors.
(4) See Safe Operating Area curves or contact the factory for the appropriate derating.
(5) The case pins on through-hole package types (suffixes N & A) must be soldered. For more information consult the applicable package outline drawing.
Input/Output Capacitors: The PT6340 regulator series requires a 100µF electrolytic (or tantalum) capacitor at the input and 330µF at the output for proper
operation in all applications. In addition, the input capacitance, Cin, must be rated for a minimum of 740mArms of ripple current, and the ESR of the output
capacitor, Cout, must less than 50mΩ @100kHz. For transient or dynamic load applications additional output capacitance may be necessary. For more information
consult the related application note on capacitor recommendations.

The PT6340 series are high efficiency regulators that
are designed to operate off a 12V input bus. These devices
incorporate an inhibit function, which may be used in
applications that require a power-up/shutdown feature.

The inhibit function is provided by the Inhibit* control,
pin 1. If pin 1 is left open-circuit the regulator operates
normally, and provides a regulated output whenever a valid
supply voltage is applied to Vin (pins 2– 4) with respect

to GND (pins 5–8). If a low voltage is then applied to
Inhibit
pin 1 the regulator output will be disabled and the input
4
current drawn by the ISR will typically drop to 0.5mA .
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 Q1 on
applies a low voltage to the Inhibit* control (pin 1) and
disables the regulator ouput. Correspondingly, turning
Q1 off 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 30ms. The waveform of Figure 2
shows the output voltage response of a PT6342 (3.3V)
following the turn-off of Q1. The turn off of Q1 corre-
sponds to the rise in Vinh. The waveforms were measured
with a 12Vdc input voltage, and 2 ½ Adc load.
The Inhibit* input can be controlled with an open-collector
(or open-drain) discrete transistor (See Figure 1). The
1
input is internally pulled-up to the input voltage, Vin
Table 1 gives the control voltage requirements.

Notes:

resistor. The open-circuit voltage of the Inhibit* input is
typically the input voltage, Vin.
2. The inhibit control input is Not compatible with TTL
devices. An open-collector device, preferably a discrete
bipolar transistor (or MOSFET) is recommended. To
ensure the regulator output is disabled, the control pin
must be pulled to less than 0.6Vdc with a low-level
0.5mA sink to ground.

3. An external source voltage can be used to control the
Inhibit* pin. To guarantee the inhibit and enable status
of the regulator, the source must be capable of meeting
the voltage requirements in Table 1 .

4. When the regulator output is disabled the current drawn
from the input source is typically reduced to 0.5mA.

Capacitor Recommendations for the PT6340
6A Excalibur™ Regulator Series
Input Capacitors:
Tantalum Capacitors
Output Current ≤4A Continuous (Table 1)
Tantalums are acceptable on the output bus but only the
AVX TPS series, Sprague 593D/594/595 series or Kemet
T495/T510 series. These capacitors are recommended
over many other 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 exhibits considerably higher ESR and lower ripple
current capability. The TAJ series is also less reliable than
the TPS series when determining power dissipation
capability. Tantalum or Oscon capacitor types are recom-
mended for applications where ambient temperatures fall
below 0°C.
The recommended input capacitance is determined by
740 milli-amperes (rms) minimum ripple current rating,
less than 100mΩ ESR (equivalent series resistance),
and 100µF minimum capacitance. The ripple current
rating, ESR, and operating temperature are the major
considerations when selecting the input capacitor.
It is recommended that tantalum capacitors have a
minimum voltage rating of twice (2×) the maximum dc
voltage, plus the ac ripple. This is necessary to insure
reliability with 12V input voltage bus applications. None
of the 100µF tantalum capacitors were found to meet
this requirement.
Capacitor Tables
Table 1 and Table 2 identify the vendors with acceptable
ESR and maximum allowable ripple current (rms) ratings.
The output capacitors are identified in both tables under
the “Output Bus” column with the required quantity.
Input Capacitors:
Output Current >4A Continuous (Table 2)
The recommended input capacitance is determined by
1.0 amperes (rms) minimum ripple current rating and
100µF minimum capacitance. The ripple current rating,
combined with less than 100mΩ ESR (equivalent series
resistance) value are the major considerations, along
with temperature, when selecting the input capacitor.
The input capacitors are listed in both tables. Table 1 has
the recommended input capacitors when operating the
ISR at a load current of 4Adc or less, and Table 2 identi-
fies input capacitors for ISR load currents greater than
4Adc.
It is recommended that tantalum capacitors have a
minimum voltage rating of twice (2×) the maximum dc
voltage, plus the ac ripple. This is necessary to insure
reliability for 12V input voltage bus applications. None
of the 100µF tantalum capacitors were found to meet
this requirement.
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.
Output Capacitors:
Output Current 0–6A (Table 1 & Table 2)
The ESR of the required capacitor must be less than,
or equal to 50mΩ. Electrolytic capacitors have poor
ripple performance at frequencies greater than 400kHz
but excellent low frequency transient response. Above
the ripple frequency, ceramic decoupling 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’s part numbers are identified in the capacitor
tables.

PT6340 Series
Adjusting the Output Voltage of the PT6340
Excalibur 6 A, 12 V Bus Step-Down ISRs
The values of (R1) [adjust down], and R2 [adjust up], can
also be calculated using the following formulas. Refer to
Figure 1 and Table 2 for both the placement and value of the
required resistor; either (R1) or R2 as appropriate.
The output voltage of the PT6340 Series ISRs may be
adjusted higher or lower than the factory trimmed pre-
set voltage with the addition of a single external resistor.
Table 1 accordingly gives the allowable adjustment range
for each model for either series as Va (min) and Va (max).

Adjust Up: An increase in the output voltage is obtained by
adding a resistor R2, between pin 12 (Vo adj) and pins 5-8
(GND).

Adjust Down: Add a resistor (R1), between pin 12 (Vo adj) and
