The LTC3816 is a single-phase synchronous step-down DC/DC switching regulator controller that drives N-channel power MOSFETs in a constant-frequency voltage mode architecture. The controller’s leading edge modulation topology allows extremely low output voltages and supports a phase-lockable switching frequency up to 550kHz. The output voltage is programmed using a 7-bit VID code.

The LTC3816 features all of the IMVP-6/IMVP-6.5 requirements, including start-up to a preset boot voltage, differential remote output voltage sensing with programmable active voltage positioning, IMON output current reporting, power optimization during sleep state, and fast or slow slew rate sleep state exit.

Fault protection features include input undervoltage lockout, cycle-by-cycle current limit, output overvoltage protection, and PWRGD and overtemperature flags.
