MAX17020 Datasheet (Maxim Integrated Products) - Dual Quick-PWM Step-Down Controller

MAX17020, Dual Quick-PWM Step-Down Controller

The MAX17020 is a dual Quick-PWM™ step-down power-supply (SMPS) controller with synchronous rectification, intended for main 5V/3.3V or I/O 1.5V/1.05V power generation in battery-powered systems.

Lowside MOSFET sensing provides a simple low-cost, highly efficient current sense for valley current-lim

MAX17020 Features

* this current limit ensures robust output supplies. The 5V/3.3V or 1.5V/1.05V SMPS outputs can save power by operating in pulse-skipping mode or in ultrasonic mode to avoid audible noise. Ultrasonic mode forces the controller to maintain switching frequencies greater than 20kHz at light loads. An in
