FAE Expert Insights
"The AP360Y extends the AP360X capabilities to higher currents while maintaining simplicity. The TO-252 package provides better thermal performance for the higher power dissipation. I've used this in automotive lighting applications. Proper heatsinking is important at 300mA - ensure adequate copper area or external heatsink. The thermal protection provides safety margin."
I highly recommend the AP360Y for its proven reliability and excellent performance in real-world applications.

Frequently Asked Questions
What is the maximum current?
The AP360Y can deliver up to 300mA constant current, suitable for high-power LEDs or multiple LED strings in parallel. For detailed specifications and application support on chipown AP360Y, refer to the datasheet or contact our team.
Use for high-power LED applications.
What thermal management is needed?
At 300mA, thermal management is critical. Use adequate PCB copper area (thermal pad connection) or external heatsink to keep junction temperature within limits. For detailed specifications and application support on chipown AP360Y, refer to the datasheet or contact our team.
Proper heatsinking required for 300mA operation.
What package is used?
The AP360Y uses a TO-252 (DPAK) package with exposed thermal pad for improved heat dissipation compared to smaller packages. For detailed specifications and application support on chipown AP360Y, refer to the datasheet or contact our team.
TO-252 provides better thermal performance.
Can it drive multiple LED strings?
Yes, multiple LED strings can be connected in parallel, each with its own AP360Y driver. Do not connect LEDs directly in parallel without individual current regulation. For detailed specifications and application support on chipown AP360Y, refer to the datasheet or contact our team.
Use separate driver for each parallel string.
What is the power dissipation at 300mA?
Power dissipation = (VIN - VLED) × 0.3A. For example, with 12V input and 3V LED: Pd = (12-3) × 0.3 = 2.7W. Ensure thermal design can handle this. For detailed specifications and application support on chipown AP360Y, refer to the datasheet or contact our team.
