Add To BomMAX77839CEFQ+ General Description
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.
