Description

Ordering Information

PT 6981o = +2.5/1.8 Volts

PT 6982o = +3.3/2.5 Volts

PT 6983o = +3.3/1.8 Volts

PT 6984o = +3.3/1.2 Volts

PT 6985o = +2.5/1.2 Volts

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.
