Description

General part information

PTB48520W Series

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 atVoBusrises first, allowing this output to provide input power to any downstream non-isolated module. The voltage fromVoSeqis 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. The wide output adjust enables the output voltage to be set to to any voltage over the range, 1.8 V to 3.6 V, using a single external resistor. Precise output voltage regulation is ensured with a differential remote sense that intelligently regulates the sequenced output, depending on its sequence status. Other operational features include an input undervoltage lockout (UVLO) and an output enable control. Overcurrent, overvoltage, and overtemperature protection ensures the module ability to survive any load fault.
