February 19, 2025Introducing RSM3502: High Efficiency, Non-Isolated, Fixed 4:1 Ratio, 1000W, Digital DC/DC Power Module

Introducing RSM3502 High Efficiency, Non-Isolated, Fixed 41 Ratio, 1000W, Digital DCDC Power Module
We proudly introduce the RSM3502, a high-efficiency, non-isolated power module with a fixed 4:1 transformer turns ratio. The module operates from a 40V to 60V DC primary bus and a 10V to 15V output voltage. It can deliver up to 1000W continuous and 2000W in transient.
The built-in digital controller can store and restore module configurations. The fault status, input voltage, output voltage, output current, and temperature can be easily monitored via the PMBus interface.
The RSM3502 is available in an LGA (23mm x 17.4mm x 8mm open frame, 23mm x 17.4mm x 10mm with HSP) package.
