Instructions for Using FAN2514S33X:
Input Voltage (VIN):
- Ensure the input voltage is within the range of 4.5V to 16V.
- Use appropriate input filtering capacitors to stabilize the input voltage.
Output Voltage (VOUT):
- The output voltage can be set using a feedback resistor divider connected to the FB pin.
- Calculate the resistor values using the formula: VOUT = VREF * (1 + R1/R2), where VREF is typically 0.8V.
Switching Frequency (fSW):
- The switching frequency is fixed at 600kHz.
- This helps in selecting the appropriate inductor and capacitor values for the output filter.
Quiescent Current (IQ):
- The quiescent current is typically 1.2mA at 5V input with no load.
- This value should be considered when designing the power supply for low-power applications.
Load Regulation:
- The load regulation is 0.5% over the load range from 10mA to 1A.
- Ensure that the load does not exceed 1A to maintain the specified performance.
Line Regulation:
- The line regulation is 0.1% per volt over the input voltage range from 4.5V to 16V.
- This ensures stable output voltage even with variations in input voltage.
Dropout Voltage (VDROPOUT):
- The dropout voltage is typically 0.3V at 1A output current and 5V input.
- This parameter is crucial for low-voltage applications where the input and output voltages are close.
Soft-Start Time (tSS):
- The soft-start time is typically 2ms.
- This helps in reducing inrush current and stress on the components during startup.
Thermal Shutdown Temperature (TSD):
- The device will shut down if the temperature exceeds 160°C.
- Ensure proper heat dissipation and cooling to prevent thermal shutdown.
Short-Circuit Protection:
- The device has built-in short-circuit protection with auto-restart functionality.
- In case of a short circuit, the device will automatically restart after a hiccup delay.
Additional Notes:
- Always refer to the datasheet for detailed information and specific application notes.
- Proper PCB layout and component selection are crucial for optimal performance and reliability.
