Description
The PT6940 Excalibur power modules
are a series of high-efficiency dual-output
regulators, housed in a solderable space-
saving package. The dual output is ideal
for DSP applications that require a second
voltage source for a processor core.
Both outputs from the PT6940 regulator
modules are rated to deliver a full 6A load
current simultaneously, and are internally
sequenced to comply with the power-up
requirements of popular DSP ICs.
Each output can be independently
adjusted with a single external resistor, and
incorporates an output sense to compensate
for voltage drop between the regulator and
load. A short-circuit load fault at either
output will result in the coordinated
shutdown of both voltages.
