Power Supply Connection:
- Connect the input voltage (VIN) to the power supply, ensuring it is within the specified range of 4.5V to 60V.
Output Configuration:
- Set the output voltage (VOUT) using external resistors connected to the feedback pin (FB). Refer to the datasheet for specific resistor values based on desired output voltage.
Frequency Programming:
- The switching frequency can be set between 300kHz and 700kHz by connecting an appropriate resistor to the RT pin.
Thermal Management:
- Ensure that the operating temperature does not exceed 125°C. Consider heat sinking if necessary.
Efficiency Optimization:
- For optimal efficiency, ensure proper component selection and layout, minimizing parasitic inductances and resistances.
Protection Features:
- The device includes overcurrent protection and thermal shutdown. No additional components are required for these features.
Storage and Handling:
- Store the device in a controlled environment where temperatures do not exceed -65°C to 150°C.
