AL8861Y-13

AL8861Y-13 is a LED driver IC in the AL8861 family. It’s a switching constant-current driver designed to power one or more LEDs from a DC input with high efficiency, using a buck/boost topology to maintain a fixed LED current as the input varies. Typical features (depending on revision) include: adjustable LED current via an external sense resistor; wide input voltage range; PWM and/or analog dimming; and protection features such as undervoltage lockout, overcurrent/short protection, thermal shutdown, and open-LED protection. It targets compact LED lighting applications (bulbs, indicators, automotive/industrial lighting). The suffix “Y-13” usually denotes a specific package, temperature grade, or production code rather than a functional change. For exact specs, consult the manufacturer’s datasheet. If you can share the vendor or a link, I can pull a precise feature list and a quick design guide.

AL8861Y-13 is a high-voltage offline LED driver IC with an integrated MOSFET for constant-current LED strings. Key features typically include:
- Integrated high-voltage MOSFET (offline operation) for direct mains drive
- Constant-current regulation via external sense resistor; adjustable LED current
- Universal input range for AC mains (wide input tolerance)
- Primary-side regulation (PSR) with efficient operation
- Soft-start to reduce inrush and prevent LED flicker
- Dimming support (PWM dimming input and/or analog/dim control)
- Protections: overcurrent/short-circuit, overvoltage, undervoltage lockout, thermal shutdown; hiccup fault mode
- High efficiency and EMI-conscious design
- Fault/status reporting and enable control pins
- Small 8-pin package (SOP-8/ similar) suitable for compact LED driver modules
Note: exact electricals (voltage ranges, current setting, switching frequency) vary by variant; consult the latest datasheet for AL8861Y-13 for precise specs.

Pin count: 13 pins.
