MAX77812  
20A User-Configurable  
Quad-Phase Buck Converter  
General Description  
Benefits and Features  
20A Maximum Output Current (5A per Phase)  
The MAX77812 is a quad-phase high-efficiency step-  
down (buck) converter capable of delivering up to 20A  
of maximum current. Programmable startup/shutdown  
sequence and user-selectable phase configurations make  
the MAX77812 ideal for powering the latest generations  
of processors. With high-efficiency and small solution  
size, the MAX77812 is optimized for space constrained  
single-cell battery powered applications.  
V Range: 2.5V to 5.5V  
IN

Range: 0.250V to 1.525V with 5mV Steps  
OUT  
±0.5% Initial Output Accuracy with Differential Sensing  
5 User-Selectable Phase Configurations  
91% Peak Efficiency (V = 3.8V, V  
= 1.1V)

IN  
Auto (SKIP/PWM) and Forced PWM Modes  
Enhanced Load Transient Response  
The MAX77812 uses an adaptive on-time PWM control  
scheme and it has SKIP and low-power SKIP modes for  
improved light-load efficiency. A programmable current  
limit reduces the overall solution footprint by optimizing  
inductors size. Differential sensing provides high output  
voltage accuracy, while enhanced transient response  
(ETR) allows fast output voltage adjustments to load tran-  
sients. Programmable soft-start/stop and ramp-up/down  
slew rate provides control over an inrush current as the  
regulator transitions between operating states.  
Programmable Ramp-Up/Down Slew Rates  
Programmable Startup/Shutdown Sequence

AR/VR Headsets and Game Consoles  
Li-ion Battery Powered Equipment  
dedicated logic inputs provide full configurability and  
control for system power optimization.  
The MAX77812 is available in 3.408mm x 3.368mm,  
64-bump 0.4mm pitch wafer-level package (WLP).
