DC2397A

DC2397A demonstration circuit features the LTC®3130-1, a wide input voltage, wide output voltage operating range, high efficiency, low noise monolithic DC/DC buck-boost converter. The LTC3130-1 has 4-pin selectable output voltages and operates from input voltages of 2.4V to 25V. The LTC3130-1 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. The LTC3130-1’s user selectable output voltages are 1.8V, 3.3V, 5.0V and 12V. To set the desired output voltage on the DC2397A, use the “VOUT JUMPER CONFIGURATION” table on the front of the board to determine the jumper settings for JP2 and JP3. The DC2397A demo board has two user selectable operating modes: Burst Mode® operation and fixed frequency PWM (JP1). In PWM Mode, the LTC3130-1 operates at 1.2MHz to allow high efficiency while minimizing the solution footprint.
