The MAX77542 is a high-efficiency step-down converter with four 4A switching phases. It uses an adaptive constant on-time (COT) current-mode control scheme and its flexible architecture supports five phase configurations. Its wide input-voltage range enables a direct conversion for less than 1V outputs from 1 to 3-cell Li+ batteries and USB power delivery (PD) supply rails. The output voltages are preset with resistors and are further adjustable through an I2C-compatible interface. Flexible sequencer and programmable soft-start/soft-stop slew rates provide controlled transitions between operating states. Programmable switching frequency, frequency tracking, and spread-spectrum features allow easier system optimization for noise-sensitive applications. Multifunction I/Os allow for flexible control of each output for EN, LPM, FPWM, POK, RSTINB, and RSTOB status. An array of built-in protections ensures safe operation under abnormal operating conditions.
