SC622AULTRT

Overview

The SC622AULTRT is an LED lighting driver IC from Semtech, featuring a charge pump topology with one output capable of delivering 400 mA. It operates within an input voltage range of 3 V to 5.5 V and supports a switching frequency of 250 kHz. The device is housed in an MLPQ-UT-20 package (3 mm x 3 mm) and functions between -40°C and +85°C.

Feature Summary

• Integrates a charge pump for LED driving with two low-dropout regulators
• Includes SemWire interface capability for system communication
• Supports automatic sleep mode with ultra-low shutdown current

Applications

• LED flash drivers for mobile devices
• Portable electronic lighting systems
• Battery-powered camera modules

Procurement Notes

Verify the specific suffix 'A' against official Semtech documentation to confirm pinout and electrical characteristics match your design requirements. Confirm RoHS compliance status directly with the manufacturer or authorized distributors before finalizing procurement orders.

Selection Notes

Select this component when a compact solution for high-current LED flash is required alongside auxiliary power rails. The integrated charge pump eliminates external inductors, while the dual LDOs provide stable voltages for other circuit sections without additional discrete components.

Part Context

This part belongs to the SC6 series of power management ICs designed for portable applications. It combines LED driving capabilities with linear regulation in a single ultra-thin package, addressing space constraints in modern handheld electronics where multiple power domains are needed.

Replacement Considerations

Consult Semtech technical support for verified cross-reference part numbers. Do not assume functional compatibility with other SC6 variants without reviewing specific datasheet differences regarding pin configurations and electrical limits.
