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 ’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. The combination of input-output isolation and a wide-input voltage range, allows operation from either +24 V or –48 V. The wideoutput 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 assured using Smart-Sense. This is a differential remote sense that will intelligently regulate the sequenced output, depending on its sequence status. Other operational features include an input under-voltage lockout (UVLO) and an output enable control. Over-current, over-voltage, and over-temperature protection assures the module’s ability to survive any load fault. Typical applications include distributed power architectures in both telecom and computing environments, particularly complex digital systems requiring powersequencing of multiple power supply rails. https://elecena.pl/product/30571894/20-a-18-60-v-input-auto-track-compatible-isolated-dc-dc-converter-erp-10 2026-08-04 https://elecena.pl/product/30571894/20-a-18-60-v-input-auto-track-compatible-isolated-dc-dc-converter-erp-10 2026-11-03
