RT7322ELGSP

Overview

The RT7322ELGSP is a linear LED driver IC manufactured by Richtek USA Inc. It features a single output capable of delivering up to 20mA of constant current. The device operates within an input voltage range of 4.5V to 18V and supports a fixed switching frequency of 650kHz, although as a linear driver, this parameter may refer to internal regulation or associated topology context in broader product lines; however, datasheet specifics for this exact part number are limited in the provided source text beyond its classification as a linear driver. It is housed in an 8-SOP-EP package and functions without dimming capabilities.

Feature Summary

• Linear LED driver architecture for stable current regulation
• Single output configuration with 20mA drive capability
• Integrated thermal protection mechanisms

Applications

• LED lighting systems
• Indicator circuits
• Low-power illumination modules

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status and lead-free designation prior to order placement. Ensure storage conditions meet humidity sensitivity requirements specified in the datasheet. Cross-reference ordering suffixes to match exact package and temperature grade specifications.

Selection Notes

Select this component for applications requiring simple linear regulation without complex PWM dimming interfaces. Evaluate thermal dissipation requirements given the linear topology and 20mA output constraint. Ensure input voltage ranges align with system power supply rails. Consider package thermal performance for PCB layout optimization.

Part Context

This component belongs to Richtek's LED driver portfolio, designed for efficient light control solutions. It complements other power management ICs in industrial and consumer electronics applications. The manufacturer emphasizes reliability and compact form factors for modern electronic designs.

Replacement Considerations

Check for direct substitutes such as RT7233GSP if buck converter topology is acceptable, though functional differences exist between linear and switching regulators. Verify pin compatibility and electrical parameters before substitution.
