DescripTion
Single-Phase Wide VIN
Range DC/DC Controller for
Intel IMVP-6/IMVP-6.5 CPUs
The LTC3816 is a single-phase synchronous step-down
DC/DCswitchingregulatorcontrollerthatdrivesN-channel
power MOSFETs in a constant-frequency voltage mode
architecture. The controller’s leading edge modulation to-
pology 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 require-
ments, including start-up to a preset boot voltage, differ-
ential 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.
