Product Overview

The LTC3539EDCB#TRMPBF is a synchronous step-up DC-to-DC Converter with output disconnect. Battery life is extended with a 700mV start-up voltage and operation down to 500mV once started. A switching frequency of 1MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. The current-mode PWM design is internally compensated, reducing external parts count. The LTC3539 feature a pin-enabled automatic Burst Mode® operation at light load conditions. Anti-ring circuitry reduces EMI by damping the inductor in discontinuous mode. Additional features include a low shutdown current of under 1µA and thermal overload protection.
  • Requires only 6 external components
  • Delivers 3.3V at 900mA from 2 alkaline/NiMH cells
  • Delivers 5V at 900mA from a lithium-polymer battery
  • Up to 94% efficiency
  • ±1.5% Feedback voltage tolerance
  • 10µA Quiescent current
  • <1µA Logic controlled shutdown
