General 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.

Key Features

Current Mode Controller with Onboard MOSFET Drivers.
Programmable Power Up/Down Tracking.
Wide VIN Range: 3.3V to 36V (VCC = 5V).
±1% 0.6V VFB Accuracy Over Temperature.
Power Good Output Voltage Monitor.
Phase-Lockable or Adjustable Frequency: 160kHz to 700kHz.
OPTI-LOOP® Compensation Minimizes COUT.
Current Foldback and Overvoltage Protection.
Selectable Continuous, Discontinuous or Burst Mode® Operation at Light Load.
Programmable Phase Opera.
