LT3502AEMS#PBF

Overview

The LT3502AEMS#PBF is a current mode PWM step-down DC/DC converter manufactured by Analog Devices Inc. It features an internal 500mA power switch and operates at switching frequencies of 1.1MHz or 2.2MHz. The device accepts input voltages from 3V to 40V and provides an adjustable output voltage range from 0.8V to 36V. It is housed in a 10-lead MSOP package with exposed pad (EP). This component is designed for automotive applications, offering efficient voltage regulation in a compact form factor suitable for space-constrained designs.

Feature Summary

Integrates a 500mA power switch within a current mode PWM control architecture
Operates at high switching frequencies of 1.1MHz or 2.2MHz to minimize external component size
Supports wide input voltage ranges up to 40V for versatile power supply applications

Applications

Automotive electronic systems requiring isolated or non-isolated buck conversion
Point-of-load regulation in industrial equipment
Battery-powered devices needing efficient step-down voltage conversion

Procurement Notes

Verify the specific suffix and tape/reel specifications against the official datasheet before ordering. Confirm that the MSOP-10 package variant matches your PCB footprint requirements. Ensure the automotive grade qualification aligns with your system's environmental standards. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a compact solution with integrated high-current switching capability is required. The choice between 1.1MHz and 2.2MHz variants depends on the desired trade-off between inductor size and electromagnetic interference. Consider the thermal performance of the MSOP package for your specific power dissipation needs. Verify input voltage compatibility with your source power supply.

Part Context

This part belongs to the LT3502 family of step-down regulators from Analog Devices. It shares architectural similarities with other members like the LT3502, differing primarily in specific electrical characteristics or packaging options. The family is designed for applications demanding small footprints and high efficiency in DC/DC conversion tasks.
