TB6865AFG

TB6865AFG is a power-management IC typically used as a switch-mode LED driver / buck regulator. It combines a switching regulator with a constant-current LED drive, making it suitable for LED backlighting in displays and compact lighting applications.
Key points:
- Integrated MOSFET with a control circuit for driving an LED string at a set current.
- Features often include wide input range, adjustable LED current via feedback, and high efficiency.
- Dimming options usually include PWM or analog control; protections such as overcurrent, undervoltage, overvoltage, and thermal shutdown are common.
- Package options are small surface-mount types used in consumer electronics.
Common applications: LCD backlights, LED lighting modules, and other small, space-constrained LED drives.
Note: exact specifications (input voltage range, max LED current, dimming interface, pinout) vary by revision and vendor. For precise details, consult the official TB6865AFG datasheet from the manufacturer. If you share the datasheet or vendor, I can summarize the exact specs.

QFN-20 package (4×4 mm), lead-free/RoHS compliant.

I’m missing the package variant. TB6865AFG pin count and pin functions depend on the package (e.g., SOP-28, QFN-28). Please specify the package or share the datasheet link, and I’ll list each pin’s function concisely.
