LT3502AEDC#TRPBF

Overview

The LT3502AEDC#TRPBF is a current mode PWM step-down DC/DC converter manufactured by Analog Devices Inc. It features an internal power switch rated for 500mA output current and operates with a fixed switching frequency of 2.2MHz. The device accepts input voltages ranging from 3V to 40V and provides an adjustable positive output voltage between 0.8V and 36V. It utilizes an 8-lead, 2mm x 2mm DFN package with an exposed thermal pad for surface mount installation. The component supports a junction temperature range from -40°C to 125°C.

Feature Summary

Integrates a 500mA power switch within a compact 2mm x 2mm DFN package
Operates at a fixed 2.2MHz switching frequency for reduced passive component size
Supports high input voltage ranges up to 40V for flexible system architectures

Applications

Portable battery-powered equipment requiring efficient voltage regulation
Industrial systems utilizing high-voltage bus lines
Embedded controllers needing compact power solutions

Procurement Notes

Verify the specific suffix 'EDC' indicates the extended industrial temperature grade (-40°C to 125°C) compared to standard commercial variants. Confirm the '#TRMPBF' or similar tape-and-reel packaging designation matches production requirements. Ensure compatibility with the 2.2MHz fixed frequency operation when designing external inductors and capacitors.

Selection Notes

Select this component when space constraints necessitate a small footprint combined with high input voltage tolerance. The 2.2MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the load current does not exceed the 500mA limit and that the thermal design accommodates the exposed pad for adequate heat dissipation under maximum load conditions.

Part Context

This part belongs to the LT3502 family of monolithic buck converters. The LT3502 series offers integrated switches in tiny packages, distinguishing it from discrete solutions. The 'A' variant typically denotes specific performance enhancements or extended operating ranges compared to the base model, focusing on reliability in demanding environments.
