Product Overview

The LTC3427EDC#TRMPBF is a high-efficiency fixed frequency step-up DC-to-DC converter with true output disconnect. Requiring minimal external components, the LTC3427 operates from an input voltage as low as 1.8V. The LTC3427 contains an internal 0.525R N-channel MOSFET switch and a 0.575R P-channel MOSFET synchronous rectifier, which enables it to supply 200mA at 3.3V from a 2-cell alkaline battery input. The LTC3427 limits inrush current during start-up and provides a soft-start of VOUT. A switching frequency of 1.25MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors and produces very low VOUT ripple. The current-mode PWM design is internally compensated, reducing external parts count. Anti-ringing control reduces EMI in discontinuous mode operation. The LTC3427 also features low shutdown current of under 1µA and thermal shutdown.
