DC3145A

Demonstration circuit 3145A demonstrates a high efficiency thermoelectric cooler driver and features the LT®8722 monolithic driver. The input voltage range of the DC3145A is from 3.1V to 15V and the output is a SPI programmable differential voltage output. The maximum output current is 4A. The switching frequency SPI programmable from 500KHz to 3MHz. The LT8722 is controlled through an SPI interface and therefore the demonstration circuit is also setup to interface through SPI.

• The (JP2) connector is intended to connect to the DC2026C through a ribbon cable
• The (JP1) jumper has two positions ENABLE and LIN
• The (JP3) jumper has two positions MANUAL and LIN
• 92.6% efficiency
