MAX17101 Datasheet (Maxim Integrated Products)

MAX17101, Step-Down Controller

The MAX17101 is a dual Quick-PWM™ step-down power-supply (SMPS) controller with synchronous rectification, intended for main 5V/3.3V power generation in battery-powered systems.

Low-side MOSFET sensing provides a simple low-cost, highly efficient current sense for providing valley current-limit prot

MAX17101 Features

* this current limit ensures robust output supplies. The 5V/3.3V 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 internal 100mA l
