The LT3502AEDC is a current-mode PWM buck DC/DC converter with an internal 500mA power switch, housed in a compact 8-pin 2mm x 2mm DFN package. The wide input voltage range of 3V to 40V makes the LT3502/LT3502A ideal for regulating power from various sources, including 24V industrial power supplies and automotive batteries. Its high operating frequency allows the use of compact, low-cost inductors and capacitors, resulting in an extremely compact solution. A constant frequency above the AM band avoids interference with radio reception, making the LT3502AEDC particularly suitable for automotive applications.
Cycle-by-cycle current limiting and frequency foldback provide protection against short-circuit outputs. Soft start and frequency foldback eliminate input inrush current during startup. DA current sensing provides additional protection under fault conditions. An internal boost diode reduces the number of components.
