LINEAR TECHNOLOGY  DC1341A  演示板, LT3757 SEPIC转换器

The is a Demonstration Board for LT3757EDD a 300kHz SEPIC converter circuit designed for 5V output from a 4.5V to 36V input. The LT3757EDD operates over an input range of 2.9V to 40V, suitable for applications from single-cell lithium- ion battery portable electronics up to high voltage automotive and industrial power supplies. It also exhibits low shutdown quiescent current of 1µA, making them an ideal fit for battery-operated systems. The IC integrates a high voltage, low dropout linear LDO regulator. Thanks to a novel FBX pin architecture, the LT3757EDD can be connected directly to a divider from either the positive output or the negative output to ground. They also pack many popular features such as soft-start, input undervoltage lockout, adjustable frequency and synchronization.
