Description
The PT6935 Excalibur series of
power modules are dual output integrated
switching regulators (ISRs) designed to
power the latest mixed signal ICs. The
dual output provides power for both the
digital I/O logic and a DSP core from a
single module. Both output voltages are
internally sequenced during power-up
and power-down to comply with the
requirements of the latest DSP chips. Each
output is independently adjustable or can be
set to at least one alternative bus voltage
with a simple pin-strap. The modules are
made available in a space-saving solder-
able case. Features include an output
current limit and short-circuit protec-
tion.
