Instructions for Use
Input Voltage (VIN):
- Ensure the input voltage is within the range of 4.5V to 18V.
- Use appropriate decoupling capacitors (e.g., 10μF ceramic) close to the input pins to filter out noise.
Output Voltage (VOUT):
- Set the output voltage using the feedback resistor network. The formula for setting the output voltage is: [ V_ = V_ left(1 + fracright) ] where ( V_ ) is typically 0.8V.
Switching Frequency (fSW):
- Adjust the switching frequency by selecting an appropriate external resistor (RT). The formula for setting the switching frequency is: [ f_ = frac{1.1 times 10^6} ] where ( R_T ) is in ohms.
Quiescent Current (IQ):
- The quiescent current is the current drawn by the IC when it is active but not driving any load. It is typically around 1.5mA.
Shutdown Current (ISD):
- To put the IC into shutdown mode, pull the SHDN pin low. The shutdown current is typically around 1μA.
Load Regulation:
- The load regulation is the change in output voltage with respect to changes in load current. It is typically around 1%.
Line Regulation:
- The line regulation is the change in output voltage with respect to changes in input voltage. It is typically around 0.1% per volt.
Efficiency (η):
- The efficiency of the converter depends on the input and output conditions. For example, at VIN = 12V, VOUT = 5V, and IOUT = 1A, the efficiency is typically around 90%.
Output Ripple Voltage (Vrpp):
- The output ripple voltage is the peak-to-peak voltage variation on the output. It is typically around 20mVp-p.
Transient Response:
- The transient response is the change in output voltage during a sudden load change. For a 1A step, the typical transient response is around 50mV.
Thermal Shutdown Threshold (TSD):
- The IC will shut down if the junction temperature exceeds 160°C to prevent damage. Ensure proper heat sinking or cooling if operating under high load conditions.
Additional Notes
- Always refer to the datasheet for detailed specifications and application notes.
- Use appropriate inductors and capacitors to ensure stable operation and meet the design requirements.
- For optimal performance, follow the recommended PCB layout guidelines provided in the datasheet.
