Description
The PT6980 Excalibur series of
power modules are dual output integrated
switching regulators (ISRs) specifically
designed to power mixed signal ICs.
Operating from a 12-V input bus, 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 inde-
pendently 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 solderable case.
The features include output current limit
and short-circuit protection.
