The PT6980 series is a dual output integrated switching regulator (ISR) designed specifically 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.
The PT6980 Excalibur™ series consists of dual output integrated switching regulators (ISRs) specifically designed to power mixed signal ICs. Operating from a 12-V input bus, the module provides two independent outputs for digital logic and a DSP core. Both output voltages are internally sequenced during power-up and power-down to comply with DSP chip requirements.
