LTC3429BES6#TRMPBF Products

The LTC3429/LTC3429B are high efficiency synchronous, fixed frequency, step-up DC/DC converters with true output load disconnect, inrush current limiting and softstart in a low profile 6-lead ThinSOTTM package. These devices are 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. The LTC3429BES6 shifts automatically to power saving Burst Mode operation at light loads while the LTC3429B features continuous switching at light loads. Antiringing control circuitry reduces EMI concerns by damping the inductor in discontinuous mode.

The devices 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.
