LT3502EDC#TRMPBF

Overview

The LT3502EDC#TRMPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3V to 40V and provides a single adjustable output from 0.8V to 36V. The device delivers up to 500mA of output current and supports switching frequencies of 750kHz or 2.2MHz. Packaged in an 8-lead WDFN (2x2mm) with exposed pad, it functions within a junction temperature range of -40°C to 125°C.

Feature Summary

Integrated high-side N-channel MOSFET enables efficient synchronous rectification without external Schottky diodes.
Dual selectable switching frequencies allow optimization for either component size or transient response performance.
Internal frequency compensation simplifies design requirements by minimizing the number of external components needed.

Applications

Point-of-load regulation for industrial control systems
Power supply stages for embedded computing platforms
Voltage conversion for automotive electronics subsystems

Procurement Notes

Verify the specific suffix configuration against official Analog Devices documentation to ensure correct package type and thermal characteristics. Confirm that the ordering part number matches the required switching frequency option and lead-free compliance standards before finalizing procurement orders.

Selection Notes

Select this component when designing compact power solutions requiring wide input voltage tolerance and moderate current delivery. Evaluate the trade-off between 750kHz and 2.2MHz operation based on available board space for inductors versus the need for faster load transient response capabilities.

Part Context

This part belongs to the LT3502 family of monolithic synchronous buck converters designed for high-efficiency applications. It integrates the controller, drivers, and power switches into a single compact package, reducing the overall solution footprint compared to discrete designs while maintaining robust performance under varying load conditions.
