描述

The MAX77540 is a high-efficiency step-down converter with two 3A switching phases. It uses an adaptive COT (constant on-time) current-mode control architecture and the two 3A switching phases can be configured as either one (2Φ, 6A) or two (1Φ, 3A each) outputs. Its wide input voltage range enables a direct conversion for sub-1V outputs from 3-cell Li+ batteries, USB PD, and 12VDC supply rails. The output voltages are preset with resistors and are further adjustable through an I2C-compatible interface. With 94% peak efficiency, low quiescent current, and compact solution size, the MAX77540 is ideal for battery powered, space-constraint equipment.

Programmable switching frequency, frequency tracking, spread-spectrum, and ultrasonic mode allow easier system optimization for noise-sensitive applications. Dedicated EN, POK, and FPWMB pins provide options for direct hardware control, while more programmable options, such as soft-start/stop and ramp-up/down slew-rates, are available through I2C. An array of built-in protections insures safe operation under abnormal operating conditions.
