LTC3773 Description
The LTC®3773 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.
