Product Overview
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. It is widely used in application such as servers, telecom, industrial power supplies, general purpose multiple rail DC/DC, FPGA and DSP requirements etc.
- Current mode controller with on-board MOSFET drivers
- Wide VIN range is 3.3V to 36V (VCC = 5V)
- Power good output voltage monitor
- OPTI-LOOP® compensation minimizes COUT
- Selectable continuous, discontinuous or Burst Mode® operation at light load
- Programmable phase operation
- Feedback voltage is 0.6V typical at (VITH = 1.2V, 0°C ≤ T ≤ 85°C)
- Shutdown current is 20μA typical at (VSDB = 0V, TA = 25°C. VCC = VDR = VBOOST = VSDB = 5V)
- Operating temperature is -40°C to 85°C
- Package style is 38-lead plastic QFN
