General Description

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.

Overview

19-4243; Rev 1; 2/09 www.DataSheet4U.com ATION KIT EVALU BLE AVAILA Dual Quick-PWM, Step-Down Controller with Low-Power LDO, RTC.

Key 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 linear regulator can be used to either generate the 5V bias needed for power-up or other lower power “always-on” suspend supplies. An independent bypass input allows automatic bypassing of the linear r.
