Instructions for L6563HTR:

1. Power Supply Connection:

   • Connect the supply voltage (Vcc) within the range of 14.5V to 30V.

2. Setting the Switching Frequency:

   • The switching frequency can be set between 65kHz and 200kHz. Adjust external components like resistors or capacitors as per the datasheet recommendations.

3. Duty Cycle Management:

   • Ensure the maximum duty cycle does not exceed 97% to prevent potential issues with the output stability.

4. Current Sensing:

   • The current sense threshold is between 0.28V and 0.32V. This helps in protecting the device from overcurrent conditions.

5. Dead Time Configuration:

   • Dead time should be configured between 0.2μs and 0.5μs to ensure proper operation and prevent shoot-through currents.

6. Propagation Delay Consideration:

   • Account for a propagation delay between 0.1μs and 0.2μs when designing the timing aspects of your circuit.

7. Capacitance Handling:

   • Use input and output capacitances as specified (20pF and 50pF typical, respectively) to maintain stability and performance.

For more detailed instructions and specific application circuits, refer to the official datasheet provided by the manufacturer.
