Description

The MAX77596 is a small, synchronous buck converterwith integrated switches. The device is designed todeliver up to 300mA with input voltages from 3.5V to24V, while using only 1.1μA quiescent current at no load(fixed-output version). Voltage quality can be monitoredby observing the active-low RESET signal. The device can operatenear dropout by running at 98% duty cycle, making it idealfor battery-powered applications.The device offers fixed 3.3V and 5V output versions, as well asan adjustable version. The adjustable version allows theuser to program the output voltage between 1V and 10Vby using a resistor-divider. Frequency is fixed at 1.7MHz,which allows for small external components and reducedoutput ripple. The device offers both forced-PWM andskip modes of operation, with ultra-low quiescent currentof 1.1μA in skip mode.The MAX77596 is available in a small (2mm x 2.5mm)10-pin TDFN package and operates across the -40°C to+85°C temperature range.ApplicationsPoint-of-Load ApplicationsPortable Devices Powered from 2s, 3s, or 4s Li+ BatteriesUSB Type-C Devices
