Triple Output Synchronous 3-Phase DC/DC Controller with Up/Down Tracking

Description

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 ratiometric 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 efficiency 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.ApplicationsServers, Telecom, Industrial Power SuppliesGeneral Purpose Multiple Rail DC/DCFPGA and DSP Requirements
