General Description  
Benefits and Features  
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 volt-  
age range of 2.3V to 5.3V. The IC provides two different  
switching current levels (1.8A and 3.1A) to optimize exter-  
nal component sizing based on given load current require-  
ments. With the 1.8A switching current-limit option, the IC  
can support up to 1.0A load current in buck mode and

OUT  
● 6μA Ultra-Low Typical Quiescent Current (At T =

+25°C)  
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.  
● 2.5MHz Nominal Switching Frequency  
● Enable Pin  
● GPIO Pins for System Design Convenience  
• FPWM (Forced PWM) Mode Selection Pin  
• POK Indicator Pin  
The IC features an adjustable output voltage, which can  
be programmed from 2.3V to 5.3V through a single resis-  
tor. 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 flex-  
ibility that allow the IC to cover a wide range of applica-  
tions and use cases while minimizing board space.  
● UVLO, Soft-Start, Active-Output Discharge,  
Overcurrent, and Thermal Shutdown Protections  
● 1.61mm x 2.01mm, 12-Bump WLP  
Ordering Information appears at end of data sheet.  
The MAX77827 is available in a 1.61mm x 2.01mm,  
12-bump wafer-level package (WLP).  
Applications  
● 1-Cell Li+ Battery Powered Equipment  
● Smartphones/Portable/Wearables  
● Internet of Things (IoT) Devices
