The EV9928-F-00B Evaluation Board is designed to demonstrate the capabilities of MP9928. The MP9928 is a high-voltage, synchronous step-down controller that directly steps down voltages from up to 60V. The MP9928 uses PWM current control architecture with accurate cycle-by-cycle current limiting and is capable of driving dual N-channel MOSFETs.
The operating frequency of the MP9928 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 MP9928 is available in TSSOP20-EP and QFN-20 (3mmx4mm) packages. This board is available in TSSOP20-EP package.
