DC1551A

Product Details

Demonstration Circuit 1551A is a wide Vin range, highly efficient, fixed frequency buck-boost converter. The unique 4-switch, single inductor architecture provides low noise and seamless operation from input voltages above, below, or equal to the output voltage. The LTC3113 features selectable PWM or Burst Mode operation and an oscillator with a programmable frequency from 300kHz to 2MHz. The LTC3113 can deliver up to 3A of continuous output current to satisfy most demanding applications. Higher output currents are possible in step-down (buck) mode. The LTC3113 operates with a 1.8V to 5.5V input and output voltage range. The demonstration board has been designed to operate over the full input voltage range, with V_OUT set to 3.3V and I_OUT of 3.0A. For V_IN < 3V, I_OUT capability is reduced.
