Product Details

Demonstration circuit 960 is a high voltage, current-mode DC/DC step-down controller featuring the LTC3824 in a small 10-pin MSOP package.

The board operates from an input voltage of 5.5V to 60V and outputs 5V @ 2A. The converter uses a P-channel MOSFET for the main switch resulting in a low parts count design. Operating frequency is set to 200kHz with the option to accept a synchronized external clock.
