Overview
The AL3069T16E-13 is a four-channel boost LED driver IC manufactured by Diodes Incorporated. It operates with an input voltage range of 4.5 V to 60 V and supports output voltages up to 80 V. The device features an adjustable switching frequency between 100 kHz and 1 MHz, delivering up to 250 mA per channel. It integrates analog and PWM dimming capabilities and includes overtemperature protection with auto-restart functionality. Packaged in a 16-TSSOP-EP (DX class) surface-mount package, it is designed for high-efficiency backlighting applications.
Feature Summary
- Four independent output channels for multi-zone LED control
- Supports both analog and pulse-width modulation dimming methods
- Integrated thermal protection with automatic restart capability
- Adjustable switching frequency ranging from 100 kHz to 1 MHz
Applications
- LCD backlight drivers for laptop computers
- Display backlight systems for televisions
- General purpose LED lighting circuits
Procurement Notes
Verify the specific suffix 'T16E-13' against the official Diodes Incorporated datasheet to confirm the TSSOP-16EP package and tape-and-reel quantity. Ensure compatibility with your PCB footprint, as the EP variant requires exposed pad soldering for thermal management. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement.
Selection Notes
Select this component when designing multi-channel LED backlight systems requiring synchronous boost conversion. It is suitable for applications needing precise current regulation across four outputs with integrated dimming controls. Consider the 16-TSSOP-EP package for its thermal performance in space-constrained designs. Verify that the required input voltage range aligns with the 4.5 V to 60 V specification.
Part Context
This part belongs to the AL3069 family of LED driver ICs from Diodes Incorporated, specialized for display backlighting. It complements other variants like the AL3069QT16E-13, which may offer automotive qualification or different packaging options. The series focuses on providing efficient power management for LCD panels in consumer electronics such as laptops and TVs.
Replacement Considerations
Check for direct substitutes within the AL3069 series, such as AL3069QT16E-13, if automotive grade is required. Evaluate pin-compatible alternatives from other manufacturers only if they match the 4-channel boost topology and 16-TSSOP-EP package dimensions.
