Product Summary
The LT3502AEDC is a Step-Down Regulator with an internal 500mA power switch, in tiny 8-lead 2mm × 2mm DFN and 10-lead MS10 packages. The wide input voltage range of 3V to 40V makes the LT3502AEDC 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. Constant frequency above the AM band avoids interfering with radio reception, making the LT3502AEDC particularly suitable for automotive applications. The applications of the LT3502AEDC include Automotive Systems, Battery-Powered Equipment, Wall Transformer Regulation, Distributed Supply Regulation.
