EVALUATION KIT AVAILABLE  
MAX77816  
High-Efficiency Buck-Boost Regulator  
with 5A Switches  
General Description  
Benefits and Features  
● Buck and Boost Operation Including Seamless  
The MAX77816 is  
a
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  
IN  
• 2.60V to 5.14V V  
with 20mV Step  
OUT  
• 3A Minimum Continuous Output Current  
(V ≥ 3.0V, V = 3.3V)

The IC features I C-compatible serial interface. The I C  
interface allows the output voltage to be dynamically  
adjusted thus enabling finer control of system power con-  
Adjustment and Provides Design Flexibility  
● 97.5% Peak Efficiency

● 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.  
• Soft-Start  
• True Shutdown™  
• Thermal Shutdown and Short-Circuit Protection  
● Multifunction GPIO Pin  
• MAX77816A: FPWM Mode Enable  
• MAX77816B: Inductor Peak Current-Limit selection  
• MAX77816C: Output Coltage Selection  
• MAX77816D: Power-OK indicator  
• MAX77816E: Interrupt Indicator  
Applications  
● Smartphones and Tablets  
● Wearable Devices  
● Wireless Communication Devices  
● RF Power Amplifiers  
● Small Size: 1.827mm x 2.127mm, 20-Bump WLP,  
● Battery-Powered Applications
