Input Voltage (VIN):
- Ensure the input voltage is within the specified range of 4.5V to 17V.
Output Voltage (VOUT):
- Set the output voltage using an external resistor divider network according to the formula provided in the datasheet.
Switching Frequency (fSW):
- Adjust the switching frequency by selecting an appropriate external resistor value for the RT pin.
Quiescent Current (IQ):
- Monitor the quiescent current to ensure it remains low when no load is present.
Efficiency (η):
- Optimize efficiency by choosing components with low resistance and minimizing parasitic losses.
Load and Line Regulation:
- Verify that the output voltage remains stable under varying load and line conditions.
Dropout Voltage (VDROPOUT):
- Ensure sufficient headroom between VIN and VOUT to avoid dropout conditions.
Thermal Shutdown (TSD):
- Check for thermal shutdown protection to safeguard against overheating.
