MAX77812EWB+T

MAX77812EWB+T is a quad-phase high-efficiency stepdown (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. 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 transients. Applications include CPU/GPU, FPGAs, and DSPs power supply, AR/VR headsets and game consoles, Li-ion battery powered equipment, space constrained portable electronics.
