Description
AI
The MAX77541 is a high-efficiency step-down converter with two 3A switching phases for single-cell Li+ battery and 5VDCsystems. 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. The output voltages are preset with resistors and are further adjustable through an I2C compatible interface. With 91% peak efficiency, low quiescent current, and compact solution size, the MAX77541 is ideal for battery powered, space-constraint equipment.Programmable switching frequency, frequency tracking, and spread-spectrum allow easier system optimization for noise-sensitive applications. Dedicated EN, POK, and FPWM 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 ensures safe operation under abnormal operating conditions.ApplicationsSingle-Cell Li+ and 5VDCSystemsGaming Consoles and VR/AR HeadsetsMicroprocessors, FPGAs, DSPs, and ASICsNetwork Switches and Routers
