Description

The PMP40042 is a D-CAP Aux. isolated power supply reference design solution for the Telecom & Server applications. High integration and low switching loss, with the UVLO, OTP, OCP, SS and Prebias Start-up, the module enables a high efficiency for 48V system application.  A low cost & compact transformer is embedded on the board. The board size is very compact (31mm * 11.9mm * 5mm). 

Features
  • Integrated high-side and low-side MOSFETs
  • Fast transient response based on the COT controlling
  • Integrated the UVLO, OTP, OCP, SS and prebias start-up
  • Wide input voltage range 36V ~ 60V
  • Compact size:  31mm * 11.9mm * 5mm
