Overview
The SC667ULTRT is a high-integrated light management unit from the Semtech SC6 series, designed for LED lighting applications. It features a Boost and Charge Pump topology with seven output channels capable of delivering up to 175 mA per channel. The device operates within an input voltage range of 2.9 V to 5.5 V and supports a switching frequency of 400 kHz. It is housed in an MLPQ-UT-20 package and functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates Boost and Charge Pump topologies for flexible LED drive configurations
- Provides seven independent current sink outputs for multi-LED arrays
- Includes four low-dropout regulators (LDOS) for auxiliary power supply
- Operates as a high-integrated light management unit with I2C control capabilities
Applications
- LED backlighting systems for displays and monitors
- General solid-state lighting fixtures
- Portable electronic devices requiring efficient LED illumination
- Automotive interior lighting applications
Procurement Notes
Verify component authenticity through authorized Semtech distributors or certified partners. Confirm that the received part matches the SC667ULTRT marking and packaging specifications. Ensure storage conditions comply with moisture sensitivity levels to prevent damage. Request relevant documentation such as RoHS compliance certificates and datasheets prior to finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring multiple LED channels driven by a single controller. Consider its dual Boost and Charge Pump architecture for applications needing both step-up and charge-pump voltage generation. Evaluate the 175 mA output current capability against specific LED forward current requirements. Ensure the system voltage falls within the 2.9 V to 5.5 V operating range for optimal performance.
Part Context
The SC667ULTRT belongs to the SC6 family of LED drivers from Semtech, which focuses on high-efficiency light management solutions. This series integrates power stages and control logic into compact packages to reduce board space. The MLPQ-UT-20 package provides thermal efficiency and fits surface-mount assembly processes commonly used in consumer electronics manufacturing.
Replacement Considerations
Consult official Semtech documentation for verified substitute part numbers. Cross-reference pin compatibility and electrical parameters before considering alternatives.
