PTB78520W 20A 输出 18-60V 输入的自动跟踪兼容的隔离 DC/DC 转换器

PTB78520W 描述

The PTB78520W is a 20-A rated, wide-input (18-60 V) 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 PTB78520W 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 PTB78520W includes many features expected of high-performance DC/DC converter modules
