6A, 6.5V, Fast-Transient, Synchronous Step-Down Converter with SS, PG and +/-1% Vfb



The MP8606 is a fully-integrated, high-frequency, synchronous, rectified step-down switch-mode converter. It offers a very compact solution to achieve 6A of continuous output current from a 2.9V-to-6.5V input with excellent load and line regulation. The advanced PWM scheme provides fast transient response and eases loop stabilization. The MP8606 integrates a 14mO high side switch and an 8mO low-side synchronous switch for high efficiency without an external Schottky diode. Fault protections include peak current limiting, hiccup over-current protection, and thermal shutdown. It also has a power-good output. The MP8606 requires a minimal number of readily available standard external components and is available in a 3mmx4mm flip-chip QFN package.
