The MP2908AGF-Z is a high-voltage, synchronous step-down controller that directly steps down voltages from up to 60V. The MP2908AGF-Z 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 light-load efficiency.The operating frequency of the MP2908AGF-Z 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 MP2908AGF-Z is available in TSSOP20-EP and QFN-20 (3mmx4mm) packages. 9icnet Electronics is an authorized Monolithic Power Systems distributor.
