Description

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 ora negative output voltage to ground. It also packs many popular features such as soft-start, input undervoltage lockout, adjustable frequency and clock synchronization in a small 10-lead MSOP package or a 3mm × 3mm QFN package.

The LT3758A data sheet gives a complete description of the part, operation and application information. The data sheet must be read in conjunction with this quick start guide for demo circuit 1342B.
