GENERAL DESCRIPTION
FEATURES
Four synchronous step down buck regulators range from 1.5A system power to 4A core power. A 100mA LDO provides a clean 1.5V to 3.6V power for auxiliary devices. All outputs support ±10% margining and the two highest power outputs support dynamic voltage control to support processors that can utilize this function to save power. Through a 400kHz I2C interface, the customer can monitor an input voltage flag and PGOOD flags for each output. The I2C port can also be used to modify power up and down sequencing options, assign PGOOD outputs to the PGOOD pins, enable outputs and select switching frequency. High switching frequency and a current mode architecture with internal compensation enable a very fast transient response to line and load changes without sacrificing stability and keeping board space to a minimum. Fault protection features include input undervoltage lockout, overcurrent protection, and thermal protection. Two pre-programmed standard products are available.
