Analog Devices LT3753 | Demoboard DC2306A

Description

Demonstration circuit 2306A is an active clamp forwardconverter featuring the LT®3753.This circuit was designed to demonstrate the high level ofperformance and efficiency that can be attained with theLT3753. It operates at 100kHz and produces a regulated54V, 1.5A output from a wide input voltage range of 10Vto 54V, making it suitable for telecom, industrial, and otherapplications. The output voltage of this circuit is jumperselectable between 54V and 48V.The DC2306 circuit features soft-start which preventsoutput voltage overshoot during startup or when recoveringfrom overload condition.
