Description

General part information

MAX77827 Series

The MAX77827 is a high-efficiency buck-boost regulator targeted for one-cell Li-ion powered applications with the lowest typical quiescent current in the industry of 6μA. 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 levels (1.8A and 3.1A) to optimize external component sizing based on given load current requirements. With the 1.8A switching current-limit option, the IC can support up to 1.0A load current in buck mode and 900mA in boost mode (VIN= 3.0V, VOUT= 3.3V).The peak efficiency of 96% makes the IC one of the best solutions as a DC/DC converter to supply a rail for battery-powered portable applications.The IC features an adjustable output voltage, which can be programmed from 2.3V to 5.3V through a single resistor. Two GPIO pins are available to support force PWM enable function and power-OK (POK) indicator. A unique control algorithm allows high-efficiency, outstanding line/load transient response, and seamless transition between buck and boost modes. These options provide design flexibility that allow the IC to cover a wide range of applications and use cases while minimizing board space.The MAX77827 is available in a 1.61mm x 2.01mm, 12-bump wafer-level package (WLP), and a 2.5mm x 2.5mm, 14-lead FC2QFN package.Applications1-Cell Li+ Battery Powered EquipmentSmartphones/Portable/WearablesInternet of Things (IoT) DevicesLPWAN (LTE/NB-IoT, LTE/Cat-M1)
