FEATURES
DESCRIPTION
Triple Output Synchronous
3-Phase DC/DC Controller with
Up/Down Tracking
The LTC3773 is a high performance, 3-phase, triple output
synchronous step-down switching regulator controller
with output voltage power up/down tracking capability.
The controller allows for sequential, coincident or ratio-
metric tracking.
This 3-phase controller drives its output stages with 120°
phase separation at frequencies of up to 700kHz per phase
minimizing the RMS input current. Light load efciency can
be maximized by using selectable Burst Mode operation.
The 0.6V precision reference supports output voltages
from 0.6V to 5V.
Fault protection features include output overvoltage, input
undervoltage lockout plus current foldback under short-
circuit or overload conditions.
