The LT3502IDC#TRMPBF is a current mode PWM step-down DC/DC converter manufactured by Analog Devices. It integrates a 500mA power switch and operates with a wide input voltage range from 3V to 40V, making it suitable for various power sources including industrial supplies and automotive batteries.
Key electrical specifications include a 500mA output current capability and a switching frequency of 1.1MHz. The device offers an adjustable output voltage and operates with a nominal input voltage of 3V and a maximum of 40V. It also features a low shutdown current of less than 2µA.
This regulator is housed in a compact 8-lead 2mm x 2mm DFN package with an exposed pad, designed for surface mounting. Its high operating frequency allows for the use of small inductors and capacitors, contributing to a small overall solution size. The constant frequency operation above the AM band helps avoid radio interference, making it suitable for automotive applications.
Additional features include soft-start, cycle-by-cycle current limiting, and frequency foldback for protection against shorted outputs and input current surges during start-up. An internal boost diode is integrated to reduce component count.
