Product Overview

The LTC3528EDDB-2#PBF is a synchronous fixed frequency step-up DC-to-DC Converter with output disconnect. High efficiency synchronous rectification, in addition to a 700mV start-up voltage and operation down to 500mV once started, provides longer run time for single or multiple cell battery-powered products. A switching frequency of 1MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. The current-mode PWM is internally compensated, simplifying the design process. The LTC3528 enters Burst Mode® operation at light loads. Anti-ringing circuitry reduces EMI by damping the inductor in discontinuous mode. Additional features include a low shutdown current, open-drain power good output, short-circuit protection and thermal overload protection.
  • Output disconnect
  • Integrated soft-start
  • Current-mode control with internal compensation
  • Burst Mode® operation with 12µA quiescent current
  • Internal synchronous rectifier
  • Logic controlled shutdown (IQ<1µA)
  • Anti-ringing control
  • Up to 94% efficiency
  • Delivers 3.3V at 200mA from a single Alkaline/NiMH cell or 3.3V at 400mA from two cells
