LT3502AEDC

Overview

The LT3502AEDC is a current mode PWM step-down DC/DC converter featuring an internal 500mA power switch. It operates with an input voltage range of 3V to 40V and provides an adjustable output from 0.8V to 36V. The device supports switching frequencies of 1.1MHz or 2.2MHz, selectable via the SYNC pin. Packaged in a compact 8-lead 2mm x 2mm DFN with exposed pad, it is designed for space-constrained applications requiring efficient voltage regulation.

Feature Summary

Integrates a 500mA power switch within a miniature footprint
Supports dual switching frequency selection for optimization
Includes thermal shutdown and current limit protection

Applications

Portable instrumentation systems
Battery-powered equipment
Industrial control modules

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with required switching frequency settings. Confirm availability status through authorized channels as distribution may vary by region.

Selection Notes

Select this component when a high-efficiency buck converter is needed with limited board space. The internal switch eliminates external inductor sizing constraints for moderate loads. Evaluate thermal performance requirements based on the small DFN package size and expected ambient conditions.

Part Context

This part belongs to the LT3502 family of monolithic switching regulators. It shares functional similarities with other Analog Devices buck converters but is distinguished by its specific 500mA rating and dual-frequency capability. The family targets applications requiring simple design and robust protection features.
