Description

The EVL9929-QW-00A is an evaluation board designed to demonstrate the capabilities of the MP9929, a high-voltage, synchronous stepdown 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 (fSW) 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.
