Instructions for Use

1. Power Supply Connection:

   • Connect the positive terminal of the power supply to the VIN pin.
   • Connect the negative terminal of the power supply to the GND pin.

2. LED Connections:

   • Connect the anode of each LED to the respective OUT1, OUT2, or OUT3 pins.
   • Connect the cathode of each LED to the GND pin.

3. PWM Control:

   • For PWM dimming control, connect the PWM signal to the PWM pin.
   • The PWM frequency should be within the range of 200Hz to 20kHz.

4. Thermal Management:

   • Ensure adequate heat dissipation by mounting the IC on a heatsink if operating at high current or in high ambient temperatures.

5. Protection Circuits:

   • The IC includes built-in overvoltage, overcurrent, and thermal shutdown protection. No external components are required for these protections.

6. Storage and Handling:

   • Store the IC in a dry, cool place within the temperature range of -65掳C to 150掳C.
   • Handle with care to avoid ESD damage. Use proper ESD protection equipment when handling the IC.

7. Testing:

   • Before final assembly, test the IC using a known good setup to ensure it meets the specified parameters.

8. Layout Considerations:

   • Keep the power supply traces short and wide to minimize voltage drops and noise.
   • Place decoupling capacitors close to the IC to filter out high-frequency noise.

9. Compliance:

   • Ensure that the design complies with relevant safety and regulatory standards for your application.
