MAX77816

High-Efﬁciency Buck-Boost Regulator

with 5A Switches

General Description

Beneﬁts and Features

● Buck and Boost Operation Including Seamless

The MAX77816 is

high-current, high-efficiency

buck-boost regulator targeting single-cell Li-ion battery-

powered applications. It supports a wide output voltage

range from 2.60V to 5.14V. The IC allows 5A (typ) maxi-

mum switch current. In buck mode, the output current can

go as high as 4A, and in boost mode, the maximum out-

put current can be 3A. A unique control algorithm allows

high efficiency, outstanding line/load transient response,

and seamless transition between buck and boost modes.

Transition between Buck and Boost Modes

• 2.3V to 5.5V V Range

• 2.60V to 5.14V V

with 20mV Step

● I C Serial Interface Allows Dynamic V

OUT

The IC features an I C-compatible serial interface. The

Adjustment and Provides Design Flexibility

I C interface allows the output voltage to be dynamically

● 97.5% Peak Efficiency

adjusted, thus enabling finer control of system power con-

● 40µA Quiescent Current

sumption. The I C interface also provides features such

as enable control and device status monitoring.

● Safety Features Enhance Device and System

Reliability

The multifunction GPIO pin is register settable to 5

different options, such as FPWM mode enable and induc-

tor peak current level selection. These options provide

design flexibility that allows the IC to cover a wide range

of applications and use cases.
