1 pcs : MP4581GN-Z - Voltage Regulators - Switching Regulators 100V, 0.8A SynchronousBuck Converter

MP4581 Synchronous Step-Down Buck Converters Monolithic Power Systems (MPS) MP4581 Synchronous Step-Down Buck Converters are high-efficiency converters with integrated power MOSFETs. The buck converters provide 0.8A of output current (IOUT) in a buck topology, derived from an input power supply of up to 100V. MP4581 features constant-on-time (COT) control, providing a fast transient response and facilitating loop stabilisation. The configurable operation frequency can be set between 100kHz to 1MHz via an external resistor. The MP4581 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 MP4581 is available in a SOIC-8EP package.
