DC1144A-A

LINEAR TECHNOLOGY  DC1144A-A  演示板, LT3580 升压/反相稳压器

is an demonstration board to evaluate the LT3580EDD boost/inverting DC/DC converter with 2A switch, softstart and synchronization. The demo circuit demonstrate small size and low component count. The boost is designed to convert a 3V-10V source to 12V at 300mA. While the inverter converts a 5V-12V to -12V at 350mA, the LT3580 is ideal for many local power supply designs. The LT3580 operates with inputs as high as 32V but in this demo board the input is limited by voltage rating of the input capacitor and magnitude of the boost output. In boost converter the input needs to be less than output. It includes many other features such as synchronization to external clock, user configurable undervoltage lockout, softstart, frequency foldback, and it is easily configured as boost or inverting converter.
