Product Overview

The LTC3773EUHF#PBF is a 3-phase synchronous step-down Switching Regulator Controller with output voltage power up/down tracking capability. This high performance triple output controller allows for sequential, coincident or ratio metric tracking. This 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 0.6 to 5V. Fault protection features include output overvoltage, input under voltage lockout plus current foldback under short-circuit or overload conditions.
  • Current mode controller with on board MOSFET drivers
  • Programmable power up/down tracking
  • ±1% 0.6V VFB accuracy over temperature
  • Power good output voltage monitor
  • OPTI-LOOP® Compensation minimizes COUT
  • Current foldback and overvoltage protection
  • Selectable continuous, discontinuous or Burst Mode® Operation at light load
  • Programmable phase operation
