Product Overview

The LTC3526LBEDC-2#TRMPBF is a synchronous fixed frequency step-up DC-to-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. A switching frequency of 2MHz 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 LTC3526LB-2 features fixed frequency operation for low noise applications. Anti-ring circuitry reduces EMI by damping the inductor in discontinuous mode. Additional features include a low shutdown current of under 1µA and thermal shutdown.
  • Output disconnect
  • Integrated soft-start
  • Current-mode control with internal compensation
  • Low noise PWM operation
  • Internal synchronous rectifier
  • Logic controlled shutdown (IQ<1µA)
  • Anti-ringing control
  • Up to 94% efficiency
  • Delivers 3.3V at 100mA from a single Alkaline/NiMH cell or 3.3V at 200mA from two cells
