Description
General part information
MAX77812 Series
The MAX77812 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. Programmable soft-start/stop and ramp-up/down slew rate provides control over an inrush current as the regulator transitions between operating states.A 3.4MHz high-speed I2C or 30MHz SPI interface with 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).Design Solution: How to Power Your QSFP-DD Optical Transceiver ›Design Solution: How to Make Your Portable Game Console Play Longer ›ApplicationsAR/VR Headsets and Game ConsolesCPU/GPU, FPGAs, and DSPs Power SupplyLi-ion Battery Powered EquipmentSpace Constrained Portable Electronics
