Instructions for L6563D

1. Power Supply Connection:

   • Connect the supply voltage (Vcc) between 15V and 30V to the appropriate pins.

2. Setting Switching Frequency:

   • Use an external resistor connected to the RT/CT pin to set the desired switching frequency within the range of 20kHz to 500kHz.

3. Output Configuration:

   • Ensure that the maximum output current does not exceed 1.8A to prevent damage to the device.

4. Reference Voltage Utilization:

   • The internal reference voltage of 2.5V can be used for setting up feedback loops or other precision requirements.

5. Start-up and Shutdown:

   • During start-up, ensure the start-up current is around 60μA.
   • For shutdown, the quiescent current will drop to approximately 5μA.

6. Thermal Management:

   • Monitor the operating temperature to avoid exceeding 150°C, which triggers thermal shutdown protection.

Note: Always refer to the official datasheet for detailed specifications and application notes.
