Product Details

Demonstration circuit 2585A contains two circuits featuring the LTC3290. The top LTC3290 circuit operates as a high voltage boost by using the power from two input supplies to create a higher output voltage. The bottom LTC3290 circuit operates as a V_IN tracking supply by using the power from an auxiliary supply input (V_AUX) and regulating a voltage above the V_IN supply input. The wide V_IN/V_AUX range allows two voltages to be used together to efficiently create a third voltage, boost from a single supply to boost, or regulate above a variable input voltage like a battery.

The high efficiency boost circuit has three selectable outputs, 15V, 24V, or 42V. If a different output is desired then the top resistor, R2, and/or the bottom resistor, R6, can be changed to provide a different output voltage. Refer to the LTC3290 data sheet and demo board schematic for more information on how to set the output voltage for the LTC3290.

The V_IN tracking circuit also has three selectable outputs, V_IN2 + 5V, V_IN2 + 10V, and V_IN2 + 15V. If a different output voltage is desired, then R9 and/or R13 can be changed to set a different output. Refer to the LTC3290 data sheet for more information on how to set the output voltage in V_IN tracking mode.

The LTC3290 can use two separate supplies or a single supply connected to both inputs for either circuit. This can be useful to boost or track a battery voltage with a regulated output.

The LTC3290 data sheet gives a complete description of the device, operation and application information. The data sheet must be read in conjunction with this demo manual.
