Description

General part information

MAX77597 Series

The MAX77597 is a small, synchronous buck converter with integrated switches. The device is designed to deliver up to 300mA with input voltages from 3.5V to 36V, while using only 1.1µA quiescent current at no load (fixed-output version). Voltage quality can be monitored by observing the active-low RESET signal. The device can operate near dropout by running at 98% duty cycle, making it ideal for battery-powered applications.The device offers fixed 3.3V. Frequency is fixed at 1.7MHz, which allows for small external components and reduced output ripple. The device offers both forced-PWM and skip modes of operation, with ultra-low quiescent current of 1.1µA in skip mode.The MAX77597 is available in a small (2mm x 2.5mm) 10-pin TDFN package and operates across the -40°C to +85°C temperature range.ApplicationsPortable Devices Powered from 2s, 3s, or 4s Li+ BatteriesUSB Type-C DevicesPoint-of-Load Applications
