概述

Description

AL8861Y-13 is a LED driver IC used in lighting to deliver a stable, current-regulated drive to LED strings. It typically combines a switching regulator with current sensing to achieve high efficiency in compact designs. Key capabilities often include:
- Constant-current regulation with external sense resistor
- Dimming options (PWM and/or analog)
- Wide input voltage range
- Protection features (overcurrent, overvoltage, short-circuit protection, thermal shutdown)
- Minimal external components for a compact LED driver
Common applications: LED bulbs, tubes, downlights, and signage.
Package: small SMD, available in standard packaging (pinout varies by vendor).
Note: exact specs, pinout, and features can vary by vendor and revision; consult the specific vendor datasheet for the -13 variant.

Package

AL8861Y-13 uses an 8-pin surface-mount package—commonly SOP-8 (also available as MSOP-8 depending on vendor). For exact dimensions, check the datasheet.

Pinout

- Pin count: 13 pins (13-pin package)
- Function: LED driver IC (DC-DC converter with constant-current output for driving LED strings)

Application

Common applications: constant-current LED driver for white LEDs in lighting fixtures (bulbs, strips, tubes), LCD/backlight edge lighting, signage and decorative lighting, automotive interior lighting, and compact switch‑mode power supplies / DC‑DC converters.
