SC627AULTRT

Overview

The SC627AULTRT is an LED lighting driver IC from Semtech, featuring a charge pump topology and five output channels. It operates within a supply voltage range of 3 V to 5.5 V at a switching frequency of 250 kHz. The device delivers an output current of 800 mA and is housed in an MLPQ-UT-20 package.

Feature Summary

• Integrates a high-efficiency charge pump with multiple programmable current sinks for precise LED control.
• Supports flexible charge pump modes including 1x, 1.5x, and 2x configurations to optimize performance across varying load conditions.
• Includes dedicated flash LED driver capabilities with automatic timeout protection to prevent overheating.

Applications

• Mobile phone camera flash systems
• Smartphone backlight illumination
• Portable electronic devices requiring efficient LED management

Procurement Notes

Verify the specific suffix 'A' against the official Semtech datasheet to confirm pinout or electrical parameter variations compared to standard variants. Confirm availability directly with authorized distributors as stock levels fluctuate. Ensure the MLPQ-UT-20 package footprint matches your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when designing single-cell Li-ion battery powered devices that require integrated charge pumping and multiple current sinks. Compare output current requirements against the 800 mA limit. Evaluate thermal performance within the MLPQ-UT-20 package for your specific enclosure constraints.

Part Context

This part belongs to the SC6 series of LED light management units designed by Semtech. These components utilize mAhXLife technology to maximize efficiency in portable applications. The series typically integrates charge pumps, LDOs, and interface controls for comprehensive LED system management.

Replacement Considerations

SC621AULTRT offers similar functionality but with a lower output current rating of 500 mA instead of 800 mA. Verify if the reduced current capacity meets your application's brightness requirements before substituting.
