Product Details

Demonstration circuit 2504A is a step-down converter featuring LT8630. The LT8630 is a monolithic, variable frequency, current mode synchronous step-down switching regulator. The demo board is designed for 12V output from a 13V to 100V input. The wide input range makes it suitable for regulating power from a variety of sources, including automotive, industrial systems and telecom supplies. The power switch, compensation and other necessary circuits are inside of the LT8630 to minimize external components and simplify design.
