LT3502EDC#TRPBF

Overview

The LT3502EDC#TRPBF is a monolithic synchronous step-down DC/DC converter 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 for efficient synchronous rectification
Internal compensation simplifies external component count
Programmable soft-start limits inrush current during startup
Cycle-by-cycle current limit protects against output short circuits

Applications

Industrial control systems requiring isolated power rails
Battery-powered equipment needing efficient voltage regulation
Embedded systems utilizing microcontrollers and DSPs
Communication infrastructure power distribution networks

Procurement Notes

Verify the specific suffix configuration to ensure compatibility with required switching frequency options. Confirm package integrity upon receipt as the exposed thermal pad requires proper soldering techniques for reliable thermal dissipation. Cross-reference datasheet revision dates to validate electrical characteristics against current design specifications.

Selection Notes

Select this component when a compact solution is needed for moderate current applications with wide input voltage ranges. Evaluate thermal performance requirements carefully due to the small footprint. Ensure external inductor selection supports the chosen switching frequency while meeting saturation current needs for stable operation under varying load conditions.

Part Context

This part belongs to the LT3502 family of synchronous buck converters designed for space-constrained designs. It shares architectural similarities with other Linear Technology regulators but offers specific pinout and thermal characteristics suited for dense PCB layouts. The series targets applications balancing efficiency with minimal bill of materials complexity.
