Overview
The SC5014AMLTRT is a high-efficiency, 2-channel step-up (boost) LED driver designed for mid-size LCD display backlighting. It features an input voltage range of 4.5V to 27V and supports output voltages up to 50V. The device integrates linear current sinks with ±2% accuracy and includes phase-shifted PWM dimming capabilities. It operates within a temperature range of -40°C to +85°C and utilizes a compact 20-pin QFN package.
Feature Summary
- Integrates two high-precision linear current sinks for uniform LED string control
- Supports flexible phase-shifted PWM dimming to reduce EMI and improve linearity
- Includes comprehensive protection mechanisms such as open/short LED detection and over-temperature shutdown
Applications
- Backlighting for mid-size displays
- Ultrabooks and All-in-One PCs
- Automotive display backlighting
Procurement Notes
Verify the specific suffix 'A' against the manufacturer's official documentation to confirm pinout compatibility and functional specifications. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging requirements. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement.
Selection Notes
Select this component when designing systems requiring dual-channel LED drive with precise current matching. It is suitable for applications needing I2C interface control and phase-shifted dimming to minimize input capacitance demands. Consider the 20-pin QFN package constraints for thermal management in space-constrained enclosures.
Part Context
This part belongs to the SC5014 family of high-efficiency HB LED drivers from Semtech. It shares architectural similarities with the SC5010 but offers a reduced channel count optimized for smaller form-factor displays. The series emphasizes ultra-fast transient response and low-profile packaging for modern portable electronics.
Replacement Considerations
The SC5014MLTRT serves as a direct substitute within the same product family, offering identical functionality with potential minor manufacturing lot variations.
