DC1280A

DC1280A demonstration circuit is a dual output converter featuring the LT3471EDD in boost and inverter configurations. Both converters are powered from the same 4.5V to 10V input source. The boost converter puts out 12V at 300mA and the inverter -12V at 200mA. The LT3471 operates with inputs as high as 16V but in this demo board the input is limited by the magnitude of the Boost output. In a boost converter the input needs to be less than the output. The DC1280A is designed so that the inverting converter can easily be configured as a boost. Both circuits are designed to demonstrate the soft start feature, advantages of the 1.2MHz switching frequency and the internal 42V/1.3A switches. Both outputs on this demo board can be modified for higher voltages. Intended for applications such as digital cameras, cellular phones, palmtop computers PC cards, miniature disk drives, xDSL power supplies, flash memory products, local 5V or 12V supplies and LCD displays.

• Demo circuit demonstrates small size and low component count
