●The MAX77596ETBB+T from Maxim Integrated Products is a 24V, 300mA, buck converter with 1.1µA IQ in 10 TDFN package. It 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 24V while using only 1.1µA quiescent current at no load. 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 output. 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. Typical applications include portable devices powered from 2s, 3s, or 4s Li+ batteries, USB type-C devices and point of load applications.
