Analog Devices / Maxim Integrated MAX77812 Buck Regulator

Analog Devices MAX77812 Buck Regulator is a configurable, quad-phase, and high-current regulator for multicore application processors in smartphones and tablets. This buck regulator achieves a world-class transient response with a miniature PCB footprint using small inductors and output capacitors. The Analog Devices MAX77812 offers flexible architecture which allows user-selectable phase configurations such as 4, 3+1, 2+2, 2+1+1, and 1+1+1+1. This buck regulator features an I2C-compatible, 2-wire serial interface consisting of a bi-directional Serial Data line (SDA) and a Serial Clock Line (SCL).
