MPQ2908A Datasheet | Monolithic Power Systems

DESCRIPTION The MPQ2908A is a high-voltage, synchronous, step-down controller that directly steps down voltages from up to 60V. The MPQ2908A uses pulse-width modulation (PWM) current control architecture with accurate cycle-by-cycle current limiting and is capable of driving dual Nchannel MOSFETs. Advanced asynchronous modulation (AAM) mode enables non-synchronous operation to optimize light-load efficiency. The operating frequency of the MPQ2908A can be programmed by an external resistor or synchronized to an external clock for noisesensitive applications. Full protection features include precision output over-voltage protection (OVP), output over-current protection (OCP), and thermal shutdown. The MPQ2908A is available in TSSOP20-EP and QFN-20 (3mmx4mm) packages.
