Product Overview

The LTC3853EUJ#PBF is a high-performance triple output step-down Switching Regulator Controller that drives all N-channel synchronous power MOSFET stages. Power loss and supply noise are minimized by operating the output stages out of phase. The part can be configured as a dual phase controller plus a single phase controller if needed. The part can also be configured to provide a single 3-phase output for even higher output currents. A wide 4.5 to 24V (28V maximum) input voltage supply range encompasses most battery chemistries and intermediate bus voltages. Phase 3 can regulate output voltages up to 13.5V. A constant-frequency current-mode architecture allows for a phase-lockable frequency up to 750kHz. Independent TK/SS pins for each output ramps the output voltages and can be configured for coincident or ratiometric tracking. Current foldback limits MOSFET heat dissipation during short-circuit conditions.
  • Supports pre-biased outputs
  • Dual N-channel MOSFET synchronous driven
  • Adjustable soft-start current ramping or tracking
  • Foldback output current limiting
  • Output overvoltage protection
  • Dual power good output voltage monitors
