Instructions for Use:
Input Voltage (VIN):
- Ensure the input voltage is within the specified range (3.0V to 5.5V).
- Use a stable power supply to avoid fluctuations that could affect performance.
Output Voltage (VOUT):
- Adjust the output voltage using the external resistor divider network.
- Calculate the resistor values using the formula: ( V_ = V_ left(1 + fracright) ), where ( V_ = 0.6V ).
Output Current (IOUT):
- The maximum continuous output current is 1.5A. Ensure the load does not exceed this limit to avoid overheating or damage.
Quiescent Current (IQ):
- The quiescent current is typically 2.5μA. This is the current drawn by the IC when it is active but not supplying any load.
Shutdown Current (ISD):
- The shutdown current is typically 0.1μA. Use the shutdown pin to disable the IC when not in use to save power.
Switching Frequency (FSW):
- The fixed switching frequency is 2.2MHz. This helps in reducing the size of external components like inductors and capacitors.
Efficiency (η):
- The typical efficiency is 90% at 3.3V input, 1.8V output, and 500mA load. Higher efficiencies can be achieved with optimal design and component selection.
Dropout Voltage (VDROP):
- The dropout voltage is typically 0.2V. Ensure the input voltage is at least 0.2V higher than the output voltage to maintain regulation.
Load Regulation:
- The load regulation is typically 0.5%. This indicates the change in output voltage due to load variations.
Line Regulation:
- The line regulation is typically 0.1%. This indicates the change in output voltage due to input voltage variations.
Transient Response:
- The transient response is typically ±3%. This is the deviation in output voltage during load transients.
Thermal Shutdown (TSD):
- The device will shut down if the temperature exceeds 160°C to prevent damage. Ensure proper heat dissipation and thermal management.
Additional Notes:
- Always refer to the datasheet for detailed specifications and application notes.
- Use appropriate PCB layout practices to minimize noise and ensure stable operation.
- For high-power applications, consider adding heatsinks or other cooling solutions to manage thermal issues.
