MAX77540 16VIN/6A, Dual-Phase High-Efficiency Buck Converter | Datasheet Preview

Maxim Integrated’s MAX77540AAWV is is a high-efficiency step-down converter with two 3A switching phases. It uses an adaptive constant on-time, current-mode control architecture and the two 3A switching phases can be configured as either one or two outputs. 3 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. The MAX77540 reduces component count and board space by enabling engineers to go from a two stage power supply design in multi-cell applications.
