Product Details

Demonstration circuit 1831A is a high power constant current, constant voltage synchronous buck controller featuring the LT3763. The input of the demo board is up to 60V. The output is optimized for 10V, 10A as a LED driver. The input voltage range of the LT3763 itself is 6V to 60V.

The demo board input range is 12V to 60V, therefore, the demo board utilizes 80V MOSFETs. If an application has a maximum input voltage of 48V, 60V MOSFETs such as BSC100N06LS3, can be used for better efficiency at lower voltage range.
