Instructions for Use:

1. Power Supply Connection: Ensure the input voltage is within the specified range of 8.7V to 30V.
2. Heat Dissipation: Given the operating temperature range, ensure adequate heat dissipation to prevent overheating.
3. Component Selection: Choose external components such as transformers and diodes that can handle the peak currents and voltages expected in a flyback topology.
4. Layout Considerations: Pay attention to PCB layout guidelines to minimize noise and parasitic effects, especially around the switching node.
5. Testing: Before mass production, test prototypes under various load conditions to verify stability and performance.
6. Protection Circuits: Utilize the built-in overcurrent and thermal shutdown protections by ensuring proper design of feedback loops and component ratings.
