The LTC3400/LTC3400B are synchronous, fixed frequency, step-up DC/DC converters delivering high efficiency in a 6-lead ThinSOT package. Capable of supplying 3.3V at 100mA from a single AA cell input, the devices contain 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 features automatic shifting to power saving Burst Mode operation at light loads, while the LTC3400B features continuous switching at light loads. Antiringing control circuitry reduces EMI concerns by damping the inductor in discontinuous mode, and the devices feature low shutdown current of under 1µA.

Both devices are available in the low profile (1mm) SOT-23 package.
