The EVL9929-QW-00A is an evaluation board designed to demonstrate the capabilities of the MP9929, a high-voltage, synchronous step-down switching regulator controller.

The MP9929 is a high-voltage controller that can directly step down voltages from up to 100V. The MP9929 uses a pulse-width modulation (PWM) current control architecture with accurate cycle-by-cycle current limiting. It can drive dual N-channel MOSFET switches. Advanced asynchronous modulation (AAM) mode enables asynchronous operation and pulse-skip mode (PSM) to optimize light-load efficiency. The MP9929’s switching frequency (f_SW) can be configured via an external resistor or synchronized to an external clock for noise-sensitive applications. Fault protections include precision output over-voltage protection (OVP), output over-current protection (OCP), and thermal shutdown.

It is recommended to read the datasheet for the MP9929 prior to making any changes to the EVL9929-QW-00A.
