Product Overview

LTC3807 is a high performance step-down switching regulator DC/DC controller that drives all N-channel synchronous power MOSFET stage. 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 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. It is widely used in application such as automotive always-on systems, battery powered digital devices, distributed DC power systems etc.
  • Input supply operating voltage range is 4V to 38V
  • Wide output voltage range is 0.8V <= VOUT <= 24V
  • RSENSE or DCR current sensing
  • Phase-lockable frequency is 75KHz to 750KHz
  • Programmable fixed frequency is 50KHz to 900KHz
  • Adjustable output voltage soft-start or tracking
  • Power good output voltage monitor, output overvoltage protection
  • Low shutdown current is 14µA typical
  • Operating temperature is -40°C to 125°C
  • Packaging style is 20-lead plastic QFN
