MPS – MP2908A: 4V to 60V Input, Current Mode, Synchronous Step Down Controller


Power Regulation, Conversion and Management

The MP2908A is a high voltage, synchronous step down controller that directly steps down voltages from up to 60V.

The MP2908A uses PWM current control architecture with accurate cycle-by-cycle current limiting and is capable of driving dual N-channel MOSFETs. Advanced asynchronous mode (AAM) enables non-synchronous operation and PFM mode to optimize light-load efficiency. The operating frequency of the MP2908A can be programmed by an external resistor or synchronized to an external clock for noise-sensitive applications. Full protection features include precision output over-voltage protection (OVP), output overcurrent protection (OCP), and thermal shutdown.
