DC – DC Converter for Automotive and EV Systems

DC – DC Converter for Automotive and EV Systems

The MP9929 is a high-voltage, synchronous, step-down, switching regulator controller that can directly step-down voltages up to 100V. The MP9929 uses pulse-width modulation (PWM) current control architecture with accurate cycle-by-cycle current limiting. It is capable of driving dual N-channel MOSFET switches.
