Product Overview

The LTC3807IFE#PBF is a high-performance step-down switching regulator DC/DC Controller that drives an all N-channel synchronous power MOSFET stage. The constant frequency current-mode architecture allows a phase-lockable frequency of up to 750kHz. The 50μA no-load quiescent current extends operating run time in battery-powered systems. OPTI-LOOP® compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. The LTC3807 features a precision 0.8V reference and power good output indicator. A wide 4 to 38V input supply range encompasses a wide range of intermediate bus voltages and battery chemistries. The output voltage of the LTC3807 can be programmed between 0.8V to 24V. The TRACK/SS pin ramps the output voltages during start-up. Current foldback limits MOSFET heat dissipation during short-circuit conditions. The PLLIN/MODE pin selects among burst mode operation, pulse-skipping mode, or continuous conduction mode at light loads.
  • 50μA Low operating
  • Selectable continuous, pulse-skipping or low ripple burst mode operation at light load
  • Selectable current limit
  • 99% Duty cycle very low dropout operation
  • Adjustable output voltage soft-start or tracking
  • Power good output voltage monitor
  • Output overvoltage protection
  • 14μA Low shutdown
  • Internal LDO powers gate drive from VIN or EXTVCC
  • No current fold back during start-up
