            MAX77540 High-Efficiency Step-Down Converter
                    Analog Devices' MAX77540 converter is well-suited for battery-powered, space-constrained equipment
    

Image of Analog Devices' MAX77540 High Efficiency Step-Down Converter Analog Devices' MAX77540 is a high-efficiency step-down converter with two 3 A switching phases. It uses an adaptive COT (constant on-time) current-mode control architecture, and the two 3 A switching phases can be configured as either one (2Φ, 6 A) or two (1Φ, 3 A each) outputs. Its wide input voltage range enables a direct conversion for sub-1 V outputs from 3-cell Li+ batteries, USB PD, and 12 V_DC 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-constrained equipment.
