ADI LT3645EUD#PBF

Понижающие (Buck) (1), линейные (LDO) (1)20,8 В ~ 16 В, 500 мА3,6 В ~ 36 В

Overview

The LT3645EUD is a dual output regulator combining a 500mA buck regulator and a 200mA low dropout linear regulator (LDO). The wide input voltage range of 3.6V to 36V makes the LT3645EUD suitable for regulating power from a wide variety of sources, including 24V industrial supplies and automotive batteries. Its high operating frequency allows the use of tiny, low cost inductors and capacitors, resulting in a very small solution.

Other features of the LT3645EUD include a <2μA shutdown, short circuit protection, soft-start and thermal shutdown. The LT3645EUD is available in the thermally enhanced 16-lead (3mm × 3mm) QFN package, or a 12-lead MSE package.
