Ordering Information

Pin-Out Information

PT 6341r = 5.0 Volts

PT 6342r = 3.3 Volts

PT 6343r = 2.5 Volts

PT 6344r = 1.8 Volts

PT 6345r = 1.5 Volts

PT 6346r = 1.2 Volts

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.
