The PTB48520W is a 25-A rated, 48-V input 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 PTB48520W 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 PTB48520W includes many features expected of high-performance dc/dc converter modules.
