DC1687A - LTC3115-1 Demo Board | Sync Buck-Boost, 2.7V ≤ VIN ≤ 40V, Vout = 5V @ Up to 2A

Demonstration circuit 1687A features the LTC®3115-1, a high voltage monolithic synchronous buck-boost converter. The DC1687A demo board has two user selectable operating modes: Burst Mode® operation and forced continuous operation (fixed frequency PWM) (JP1). There is also an accurate programmable RUN pin which is used to enable the converter (JP2).

The DC1687A operates with a 2.7V to 40V input voltage range. The demo board has been designed with the output voltage set to 5.0V. The LTC3115-1 incorporates a proprietary low noise switching algorithm which optimizes efficiency with input voltages above, below or equal to the output voltage and ensures seamless transitions between operating modes.
