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, I_MON 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.
