Overview
The AL9910-3S-13 is an offline LED driver IC from Diodes Incorporated designed for high brightness LED applications. It drives external MOSFETs at switching frequencies up to 300 kHz, with the frequency determined by a single resistor. The device supports universal input voltages and features PWM dimming capabilities. It is housed in an SOIC-8 package and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Supports PWM dimming for precise light control
- Includes open LED protection for system safety
- Utilizes boost or buck topology for flexible design
Applications
- High brightness LED lighting systems
- Offline LED driver circuits
- Universal voltage LED illumination
Procurement Notes
Verify the specific suffix '3S' against the manufacturer's official datasheet to confirm pinout and functional compatibility. Ensure the component meets RoHS requirements if mandated by your assembly process. Cross-reference the Mouser part number 621-AL9910-3S-13 with the original Diodes Incorporated documentation to validate authenticity and current production status before procurement.
Selection Notes
Select this component when designing offline LED drivers requiring adjustable switching frequencies via a single external resistor. It is suitable for applications needing PWM dimming and robust protection features like open LED detection. Consider the SOIC-8 package constraints and the requirement for an external MOSFET when evaluating board space and thermal management needs.
Part Context
This part belongs to the AL99 series of LED drivers from Diodes Incorporated. The series is characterized by its ability to drive external power switches efficiently. The AL9910 variant specifically targets high brightness LED applications, offering a balance of performance and simplicity through minimal external component count.
Replacement Considerations
Check for AL9910S-13 or AL9910ASP-13 as potential variants within the same family. Verify if the '3S' suffix denotes a specific tape-and-reel configuration or a minor revision that maintains electrical equivalence. Consult the manufacturer's substitution guide for confirmed cross-references.
