Overview

The MAX77504 is a synchronous 3A step-down DC-DC converter optimized for portable 2-cell and 3-cell battery-operated applications. The converter operates on an input supply between 2.6V and 14V. Output voltage is adjustable between 0.6V and 6V 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. The SEL input easily configures switching frequency, gain, and output active discharge option. Built-in undervoltage lockout (UVLO), output active discharge, cycle-by-cycle inductor current limit, thermal shutdown, and short-circuit protection ensure safe operation under abnormal operating conditions. The MAX77504 is offered in a small 1.7mm x 1.7mm, 16-bump, 0.4mm pitch wafer-level package (WLP) or a 2.5mm x 2.5mm, 12-lead, 0.5mm pitch flip-chip QFN (FC2QFN).
