The PTB48520W is a 25-A rated, 48-V input isolated dc/dc converter that incorporates Auto-TrackTM 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 Vo Bus rises first, allowing this output to provide input power to any downstream non-isolated module. The voltage from Vo 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
