MP8770C Synchronous Step-Down Converter

The MP8770C from Monolithic Power Systems is a fully integrated, high-frequency, synchronous rectified step-down switch-mode converter with internal power MOSFETs. The device offers a very compact solution to achieve 8 A of continuous output current with excellent load and line regulation over a wide input range. It uses synchronous mode operation for higher efficiency over the output current load range. Constant on-time (COT) control operation provides a very fast transient response, easy loop design, and very tight output regulation. Full protection features include short-circuit protection (SCP), overcurrent protection (OCP), undervoltage protection (UVP), and thermal shutdown. The MP8770C requires a minimal number of readily available, standard external components and is available in a space-saving QFN-16 (3 mm x 3 mm) package.
