Input Voltage Setup:
- Ensure the input voltage is within the operating range of 4.5V to 28V.
Output Voltage Configuration:
- Adjust the output voltage using external resistors according to the datasheet formula: VOUT = VREF * (1 + R1/R2).
Switching Frequency Adjustment:
- The switching frequency can be adjusted by changing the value of an external resistor connected to the RT pin.
Thermal Management:
- Monitor the device temperature and ensure it does not exceed the thermal shutdown threshold of 160°C.
Efficiency Optimization:
- For optimal efficiency, operate within recommended input/output voltage ranges and load currents.
Quiescent Current Minimization:
- To minimize quiescent current, avoid unnecessary loads and use the device in low-power modes when applicable.
Protection Features:
- The device includes protection features such as overcurrent protection, short-circuit protection, and thermal shutdown. Verify these are functioning correctly during operation.
Capacitor Selection:
- Choose input and output capacitors with appropriate ratings to stabilize the power supply and reduce ripple.
Layout Considerations:
- Pay attention to PCB layout guidelines provided in the datasheet to ensure reliable performance and minimize noise.
