Product Overview

The LTC3526LEDC#PBF is a 550mA 1MHz synchronous Step-up DC/DC Converter with output disconnect. Battery life in single AA/AAA powered products is extended further with a 680mV start-up voltage and operation down to 500mV once started. Soft-start and inrush current limiting are provided during start-up, as well as normal mode. 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 LTC3526L features Burst Mode® operation at light load conditions allowing it to maintain high efficiency over a wide range of load. Additional features include a low shutdown current of under 1µA and thermal shutdown.
  • Delivers 3.3V at 100mA from a single alkaline/NiMH cell or 3.3V at 200mA from two cells
  • VIN start-up voltage (680mV)
  • Up to 94% efficiency
  • Output disconnect
  • 1MHz Fixed frequency operation
  • VIN > VOUT operation
  • Integrated soft-start
  • Current mode control with internal compensation
  • Burst Mode® operation with 9µA IQ
  • Internal synchronous rectifier
  • Logic controlled shutdown (IQ < 1µA)
  • Anti-ring control
