Product Overview

The LT3502AIDC#TRMPBF is a 1.1MHz 500mA Step-down Regulator with an internal 500mA power switch. The wide input voltage range of 3 to 40V makes the LT3502 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 LT3502A particularly suitable for automotive applications. Cycle-by-cycle current limit and frequency fold back provide protection against shorted outputs. Soft-start and frequency fold back eliminates input current surge during start-up. DA current sense provides further protection in fault conditions. An internal boost diode reduces component count.
