DC1342B

DC1342B is a LT3758AEMSE high efficiency SEPIC converter demonstration board. Demonstration circuit 1342B features the LT®3758AEMSE in a 300KHz SEPIC converter circuit, designed for a 24V output from a 18V to 72V input. The LT3758A operates over an input range of 5.5V to 100V suitable for automotive, telecom and industrial applications. It also exhibits a low shutdown current of 1µA making it ideal for battery-operated systems. Thanks to a novel FBX pin architecture, the LT3758A can be connected directly to a resistor divider from either a positive output voltage or a negative output voltage to ground. It also packs many popular features such as soft-start, input undervoltage lockout, adjustable frequency and clock synchronization.

• Input supply range from 18V to 72V
• Output voltage range from 23.28V to 24.72V
• Maximum output current of 1A
• Switching frequency of 300KHz
