Description

PMP9393 is a Single-Phase Synchronous Boost Converter which utilizes the LM5122 controller IC.  The design accepts an input voltage of 18Vin to 20Vin and provides an output of 48Vout capable of supplying a maximum of 3A of current to the load. DCR current sensing has been implemented in order to reduce the BOM cost associated with using a high power current sense resistor.

Features
  • Synchronous rectifier for high efficiency
  • High power density
  • Lower temp rise in output rectifier
  • Synchronizable to external clock
  • Stackable for higher output currents
  • Bypass mode capable when Vin >Vout
