Product Description

The MP8736 is a fully integrated high frequency synchronous rectified step-down switch mode converter. This device integrates a 12mO low- side FET and a 30mO high-side FET in a monolithic die. The MP8736 operates with high efficiency over a wide output current load range. Constant-On-Time (COT) control mode provides fast transient response and eases loop stabilization. The MP8736 has a programmable frequency pin to optimize system performance. Full protection features include SCP, OCP, OVP, UVP and thermal shut down. The MP8736 requires a minimum number of readily available standard external components and is available in a space saving 3mm x 4mm 20-pin QFN package.
