The MAX77504 is a synchronous 3 A step-down DC-DC converter optimized for portable 2-cell and 3-cell battery-operated applications. The converter operates on an input supply between 2.6 V and 14 V. The output voltage is adjustable between 0.6 V and 6 V with external feedback resistors. The device features a low-IQ SKIP mode that allows excellent efficiency at light loads. The MAX77504 can be synchronized by driving the FPWM pin with an external clock.

Dedicated enable, power-OK, and FPWM pins allow simple hardware control.
