Description
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.
