MP4541 Step-Down Converter

Monolithic Power Systems (MPS) MP4541 Step-Down Converter is high-efficient with integrated power MOSFETs and is available in a SOIC-8E package. This step-down converter offers 0.8A of output current (I_OUT) in a buck topology from an input power supply of up to 80V. The MP4541 features Constant-On-Time (COT) control, which provides a fast transient response and facilitates loop stabilization. This Step-Down converter supports high-efficiency Pulse-Skip Mode (PSM) while operating under light-load conditions. The MP4541 offers a configurable operation frequency that can be set between 100kHz and 1MHz via an external resistor. The MP4541 features internal soft-start and loop compensation, Over-Current Protection (OCP), Short-Circuit Protection (SCP) with hiccup mode, and High-efficiency Pulse-Skip Mode (PSM) under light load conditions. This Step-Down converter offers applications like high voltage battery packs, industrial power supplies, and printer power boards.
