Product Overview

The LTC3429ES6#TRMPBF is a high-efficiency synchronous fixed frequency step-up DC-to-DC Converter with true output load disconnect, inrush current limiting and soft-start function. This device is capable of supplying 100mA from a single AA cell input or 250mA from a 2-cell AA with a 3.3V output. A switching frequency of 500kHz minimizes overall solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. Current-mode PWM control with internal compensation reduces external parts count thereby saving critical board real estate. It shifts automatically to power-saving Burst Mode® operation at light loads. Anti-ringing control circuitry reduces EMI concerns by damping the inductor in discontinuous mode. The device also feature low shutdown current of under 1µA. The true output disconnect feature allows the output to be completely discharged in shutdown. It also limits the inrush of current during start-up, minimizing surge currents seen by the input supply.
