The LTC®3111 is a fixed frequency, synchronous buckboost 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 and output range of 2.5V to 15V, the LTC3111 is well suited for a wide vari.
