The LN3400 is a 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 1.5MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors.

automatic shifting to power saving PFM Mode operation 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 SOT-23 package.
