LTC3773EUHF#PBF

LINEAR TECHNOLOGY  LTC3773EUHF#PBF  直流/直流控制器, 3相, 3.5V至36V, 3路输出, 同步降压, 630kHz, QFN-38

The 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.
