Input Voltage Connection:
- Connect the input voltage (VIN) to the designated pin ensuring it stays within the operational range of 4.5V to 60V.
Setting the Switching Frequency:
- Adjust the external resistor connected to the RT/CT pin to set the desired switching frequency between 65kHz and 200kHz.
Minimizing Power Loss:
- Ensure the minimum on-time is not exceeded by selecting appropriate inductor values for the application.
Maintaining Stability:
- Use the compensation network as recommended in the datasheet to maintain stability across all operating conditions.
Output Voltage Configuration:
- Configure the feedback network to achieve the desired output voltage accuracy, keeping within ±1.5%.
Thermal Management:
- Ensure adequate heat sinking or PCB layout to dissipate heat effectively, especially under high-load conditions.
Protection Features:
- Utilize built-in protection features like overcurrent protection and thermal shutdown to safeguard the device from damage.
Layout Considerations:
- Follow recommended PCB layout guidelines to minimize noise and ensure reliable operation.
