Overview
The SC628AULTRT is an LED lighting driver IC from Semtech, designed for applications requiring a 1A flash current. It operates within a supply voltage range of 3 V to 5.5 V and features a charge pump topology. The device is housed in a 20-pin MLPQ-UT-20 package with dimensions of 3 mm x 3 mm and a height of 0.60 mm. It supports serial data input and functions as an LED display driver. The component is compliant with RoHS standards and operates reliably across a temperature range of -40 °C to +85 °C.
Feature Summary
- Integrates a charge pump topology to support high-current flash output capabilities
- Features ultra-thin packaging suitable for space-constrained designs
- Includes automatic sleep mode functionality to minimize power consumption
Applications
- Mobile device camera flash systems
- Portable electronic device illumination
- Compact LED lighting modules
Procurement Notes
Verify the specific ordering suffix and package variant against the manufacturer's latest datasheet before procurement. Confirm that the MLPQ-UT-20 package dimensions align with your PCB footprint requirements. Ensure compatibility with the required serial interface protocol for system integration. Check for any recent product change notifications regarding material or manufacturing site updates.
Selection Notes
Select this component when a single-channel driver with high peak current capability is required for flash applications. Consider the 3V to 5.5V input range for compatibility with standard battery voltages. Evaluate the 20-pin DFN package for thermal management and board space constraints. Compare against other SC6 series drivers if multiple channels or different topologies are needed.
Part Context
The SC628AULTRT belongs to Semtech's SC6 series of LED drivers, which are optimized for portable electronics. This series emphasizes efficiency and compact form factors. The part shares family characteristics such as low shutdown current and RoHS compliance with other members like the SC621 and SC622, but differs in its specific 1A flash output configuration and charge pump architecture.
Replacement Considerations
Publicly confirmed substitute part numbers for the SC628AULTRT are not available in the provided documentation. Verify pinout and electrical specifications carefully when considering alternative components from other manufacturers.
