Overview
The SC652ULTRT is a Semtech LED lighting driver IC featuring five output channels and charge pump topology. It operates within an input voltage range of 2.9 V to 5.5 V, delivering up to 125 mA output current per channel. The device supports PWM dimming control and functions at a switching frequency of 250 kHz. Designed for surface mount installation in MLPQ-UT-14 packages, it ensures reliable performance across temperatures from -40°C to +85°C with a maximum supply current of 2.5 mA.
Feature Summary
- Integrates five independent constant-current sink channels driven by an internal charge pump
- Supports high-frequency PWM dimming for precise backlight brightness control
- Operates efficiently on single-cell lithium-ion battery power sources
Applications
- Mobile phone LCD backlight systems
- Portable media player display illumination
- Smartphone camera flash circuits
Procurement Notes
Verify component authenticity through authorized Semtech distributors or certified partners. Confirm the specific package marking and date code against official documentation. Ensure storage conditions comply with moisture sensitivity levels prior to reflow soldering. Validate that the intended application environment remains within the specified thermal operating limits.
Selection Notes
Select this component when designing portable electronics requiring five-channel LED driving from a single-cell battery source. The integrated charge pump eliminates external inductors, reducing board space compared to boost converters. Consider the MLPQ-UT-14 footprint constraints during PCB layout planning to ensure adequate thermal dissipation for continuous operation.
Part Context
This part belongs to the Semtech SC6 series of high-efficiency LED drivers. These components are engineered specifically for mobile communication devices and portable consumer electronics. The series emphasizes compact form factors and low quiescent current consumption to maximize battery life in handheld applications.
Replacement Considerations
Consult Semtech technical support for verified substitute part numbers. Do not assume functional compatibility with other SC6 variants without reviewing specific electrical parameter differences.
