PMP41130
1.2kW hard-switching, full bridge (HSFB) telecom power supply unit
PMP41130
概述
The PMP41130 demonstrates a symmetrical hard- switching full-bridge DC-DC power converter with digital control using the UCD3138064, LMG3100, and LMG2175 devices. This Reference design includes required control functions for a hard-switched full bridge (HSFB) converter. PMP41130 accepts a DC input from 36VDC to 60VDC, and outputs a nominal 48VDC with full output load power 1200W, or full output current 25A. Peak efficiency of 96.7% achieved with 36V input voltage and 600W output condition.
特性
- Digitally controlled and standalone hard-switching full bridge DC-DC power conversion - voltage mode control.
- Protection: overvoltage, undervoltage, overcurrent, and over-temperature.
- Constant soft-start time.
- Using GaN FETs to achieve high efficiency with high switching frequency.
