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 to optimize lightload efficiency.
The operating frequency of the MP2908A 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 MP2908A is available in TSSOP20-EP and QFN-20 (3mmx4mm) packages.
