GENERAL DESCRIPTION

FEATURES

include local and remote voltage sense, primary and secondary side current sense, digital pulse-width modulation (PWM) generation, current sharing, and redundant OrFET control. The control loop digital filter and compensation terms are integrated and can be programmed over the I2C interface. Programmable protection features include overcurrent protection (OCP), overvoltage protection (OVP), undervoltage lockout (UVLO), and overtemperature protection (OTP).
