The PTB78520W is a 20-A rated, wide-input (18-60 V) isolated DC/DC converter that incorporates Auto-Track? power-up sequencing. This allows these modules to simultaneously power up with any other downstream non-isolated, Auto-Track compliant module.

The PTB78520W module provides two outputs, each regulated to the same voltage. During power up, the voltage at ’V_O Bus’ rises first, allowing this output to provide input power to any downstream non-isolated module. The voltage from ’V_O Seq’ is then allowed to rise simultaneously, under the control of Auto-Track, along with the outputs from the downstream modules.

Whether used to facilitate power-up sequencing, or operated as a stand-alone module, the PTB78520W includes many features expected of high-performance DC/DC converter modules.
