Instructions for Use:
Input Connection:
- Connect the input voltage (VIN) to the power supply.
- Ensure the input voltage is within the specified range (4.5V to 28V).
Output Configuration:
- Adjust the output voltage (VOUT) using the external resistor divider network.
- The output voltage can be set between 0.8V and 18V.
Output Load:
- The maximum continuous output current (IOUT) is 3A.
- Ensure the load does not exceed this limit to avoid damage.
Efficiency:
- The efficiency is typically 92% at full load when converting from 12V to 5V.
- Monitor the temperature and efficiency under different load conditions.
Quiescent Current:
- The quiescent current (IQ) is approximately 25μA with no load.
- This low quiescent current helps in reducing power consumption in low-power applications.
Regulation:
- Line regulation (ΔVOUT/ΔVIN) is typically 0.01% per volt.
- Load regulation (ΔVOUT/ΔIOUT) is typically 0.05% per ampere.
- These parameters ensure stable output voltage under varying input and load conditions.
Dropout Voltage:
- The dropout voltage (VDROPOUT) is typically 1.2V at full load.
- Ensure the input voltage is sufficiently higher than the output voltage to maintain regulation.
PSRR (Power Supply Rejection Ratio):
- The PSRR is typically 60dB at 1kHz.
- This helps in filtering out noise from the input power supply.
Temperature Considerations:
- The operating temperature range (TOPR) is -40°C to 125°C.
- The storage temperature range (TSTG) is -65°C to 150°C.
- Ensure the device operates within these temperature limits to avoid thermal stress.
Package Type:
- The DP8473V is available in a SOT-23 package.
- Follow standard PCB layout guidelines for SOT-23 packages to ensure reliable operation.
