功能描述

The LTC3400-1 is a synchronous, fixed frequency, stepup DC/DC converter delivering high efficiency in a 6-lead ThinSOT? package. Capable of supplying 3.3V at 100mA from a single AA cell input, the device contains an internal NMOS switch and PMOS synchronous rectifier.

A switching frequency of 1.2MHz 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 LTC3400-1 features automatic shifting to power saving Burst Mode operation at light loads. In shutdown, VOUT and VIN are connected, which allows the input battery to be used for backup power. The LTC3400-1 features low shutdown current of under 1μA.

The LTC3400-1 is offered in the low profile (1mm) SOT-23 package.
