Overview
The SC624ULTRT is an LED light management unit from Semtech, utilizing a switched capacitor charge pump topology. It features four constant current outputs designed for driving LEDs, alongside dual low-dropout regulators (LDOs). The device operates on a supply voltage range of 3 V to 5.5 V and supports a switching frequency of 250 kHz. It integrates the SemWire interface for control and is housed in a compact 20-MLPQ-UT package.
Feature Summary
- Integrates four dedicated LED output channels with dual LDOs for comprehensive light management
- Utilizes a switched capacitor charge pump topology for efficient DC-DC regulation
- Incorporates the SemWire interface for digital control and configuration
Applications
- LED backlighting systems requiring multi-channel current regulation
- Portable electronic devices utilizing charge pump based LED drivers
- Light management units integrating auxiliary power via dual LDOs
Procurement Notes
Verify the specific ordering suffix and package variant against the manufacturer's latest documentation before procurement. Confirm that the 20-MLPQ-UT footprint matches your PCB layout requirements. Ensure compatibility with the SemWire interface protocol if digital control is utilized in the design.
Selection Notes
Select this component when a single-chip solution for four LED channels and auxiliary power is required. The charge pump topology eliminates the need for external inductors, saving board space. Verify that the input voltage range of 3 V to 5.5 V aligns with the system power supply constraints.
Part Context
This part belongs to the SC6 series of LED drivers from Semtech Corporation. The series focuses on high-efficiency lighting solutions using advanced switched capacitor technologies. The SC624 specifically targets applications needing multiple regulated outputs within a small form factor.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Generic equivalents may not support the proprietary SemWire interface or the specific MLPQ-UT package dimensions.
