MP9928 Datasheet Synchronous Step-down Controller

Manufacturer: Monolithic Power Systems

Overview: The Future of Analog IC Technology.

General Description

The MP9928 is a high-voltage, synchronous step-down switching regulator controller that can directly step down voltages from up to 60V.

The MP9928 uses PWM current control architecture with accurate cycle-by-cycle current limiting.

It is capable of driving dual Nchannel MOSFET switches.
