LTC3112 Description

The LTC3112 is a fixed frequency synchronous buck-boost DC/DC converter with an extended input and output range. The unique 4-switch, single inductor architecture provides low noise and seamless operation from input voltages above, below or equal to the output voltage.

With an input range of 2.7V to 15V, the LTC3112 is wellsuited for a wide variety of single or multiple cell battery, backup capacitor or wall adapter source applications. Low RDS(ON) internal N-Channel MOSFET switches provide highly efficient operation in applications with higher load current requirements.

The LTC3112 features selectable PWM or Burst Mode operation, an easily synchronized oscillator and output disconnect in shutdown. An output current monitor circuit allows the load current to be controlled or measured. Other features include <1μA shutdown current, short circuit protection, soft-start, current limit and thermal shutdown.

The LTC3112 is offered in both a 16-pin (4mm × 5mm × 0.75mm) DFN and 20-pin TSSOP packages.
