Overview

PMP9490 is a 225W four Switch Buck –Boost Design utilizing best in Class Synchronous Buck Boost Converter LM5175.  The design accepts an input voltage of 9.5Vin to 20Vin and provides the outputs of 15V@15 A for Constant Voltage Output Application such as Voltage stabilizer or as Power amplifier SMPS, 10.8V to 15V@12.5A  for CC/CV Battery Charger application, and 12.5 A for Constant Current LED Drive application.  It features an inexpensive and more efficient solution to using discrete Buck and boost converters. The average current regulation loop of the IC at the output is used for Battery Charging profiling with no external circuit being involved.

Features
  • Four Switch Buck Boost for Efficient operation
  • Higher Efficiency Buck-Boost Transition
  • Very Low Cost Solution for CC/CV Charger or LED Driver.
  • No Extra Components needed .
  • Low Vin Support for Automotive application
  • Optional Frequency Sync and Dithering
  • Cycle-by-Cycle Current Limit and Optional Hiccup 

 

 

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
