MPM3860 from Monolithic Power Systems is a fully integrated, high-frequency, synchronous, rectified, step-down power module with an internal inductor. It offers a very compact solution to achieve 6 A of continuous output current over a wide input range with excellent load and line regulation. The device has synchronous mode operation for higher efficiency over the output current load range. Full protection features include short-circuit protection (SCP), overcurrent protection (OCP), undervoltage protection (UVP), and thermal shutdown. The MPM3860 features constant on-time (COT) control operation, providing very fast transient response and easy loop design, as well as very tight output regulation. It is available in a QFN-24 (4 mm x 6 mm) package.
