Product Description

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 over-current protection (OCP), and thermal shutdown.
The MP2908A is available in TSSOP20-EP and QFN-20 (3mmx4mm) packages.
