DC1598A - LTC3112EDHD Demo Board

Demonstration Circuit 1598A is a fixed frequency synchronous buck-boost 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.

The LTC3112 features selectable PWM or Burst Mode operation, and an easily synchronizable oscillator. An output current monitor allows the load current to be controlled or monitored. The LTC3112 operates with a 2.7V to 15V input voltage range and a VOUT range from 2.5V to 14V. The demonstration board has been designed to operate with VIN from 2.7V to 15V and an output current up to 2.5A. For VIN < 5V, IOUT capability is reduced. VOUT is set to 5.0V.
