The MP4541 is a high-efficiency, synchronous step-down converter with integrated power MOSFETs. The device provides 0.8A of output current (IOUT) in a buck topology from an input power supply of up to 80V. The MP4541 features constant-on-time (COT) control, which provides fast transient response and facilitates loop stabilization. The configurable operation .
constant-on-time (COT) control, which provides fast transient response and facilitates loop stabilization. The configurable operation frequency can be set between 100kHz and 1MHz via an external resistor.
The device supports high-efficiency pulse-skip mode (PSM) while operating under light-load conditions. The valley current limit circuits protect against overload and short-circuit conditions.
The MP4541 is available in an SOIC-8EP package.
