TI Unveils Plug-In Power Module

Dallas, TX (November 17, 2004)--Texas Instruments has unveiled the PTB78520W, a 20-A, wide-input (18 V to 60 V), isolated DC/DC plug-in power module with Auto-Track sequencing technology. The module simultaneously powers up with any downstream, non-isolated, Auto-Track-compliant, point-of-load module.

Dallas, TX (November 17, 2004)--Texas Instruments has unveiled the PTB78520W, a 20-A, wide-input (18 V to 60 V), isolated DC/DC plug-in power module with Auto-Track sequencing technology. The module simultaneously powers up with any downstream, non-isolated, Auto-Track-compliant, point-of-load module.

The PTB78520W provides greater design flexibility to 24-V and -48-V telecom and computing distributed power systems, including complex digital systems requiring power sequencing of multiple power supply rails. Achieving power conversion efficiency up to 90 percent, the module provides two high-current outputs that are both regulated to the same output voltage.

The first output incorporates soft start and a remote on/off control. The second output is switched, which allows the user to control the output voltage with the Auto-Track function. The switched output tracks the voltage present at the track I/O pin.
