Description

General part information

MAX77839 Series

The MAX77839 is a highly-efficient buck-boost regulator with an industry leading quiescent current of 6μA targeted for one-cell Li-ion and down to any battery chemistry with 1.8V discharge voltage. It supports input voltages of 1.8V to 5.5V and an output voltage range of 2.3V to 5.3V. The IC provides two different switching current limits to optimize external component sizing based on given load current requirements ("A" and "B" = 4.4A (typ), "C" and "D" = 3.6A (typ)), and two different GPIO pin configurations ("A" and "C" = FPWM pin,"B" and "D" = POK pin). These options provide design flexibility that allow the IC to cover a wide range of applications and use cases while minimizing board space.The IC features a single-resistor adjustable output voltage from 2.3V to 5.3V. A configurable GPIO pin allows to select either a FPWM mode control input or an active-low POK open drain output, depending on the system requirements. Maxim's unique buck-boost controller technology provides high efficiency, excellent load and line transient response, and a seamless transition between buck and boost modes of operation.The MAX77839 is available in both a 2.07mm x 1.51mm, 15-bump wafer-level package (WLP), and a 2.5mm x 2.0mm, 11-lead FC2QFN package.ApplicationsAsset Tracking/Fleet Management5G/2G/GSM Cellular PowerRF AmplifierSmartphones ToF/Facial and Gesture RecognitionSystem Power Pre-RegulationSingle-Cell Li-ion Battery Powered Devices
