Instructions for Using FAN4800ASNYS
Power Supply Connection:
- Connect the input voltage (VIN) to the supply voltage within the range of 2.7V to 5.5V.
- Ensure that the input voltage is stable and free from significant noise.
Output Configuration:
- The output voltage (VOUT) is regulated and should be connected to the load.
- Ensure that the load current does not exceed the maximum continuous output current of 3.0A.
Quiescent Current:
- The quiescent current (IQ) is typically 1.0mA and can increase to 1.5mA under certain conditions.
- This current is drawn from the supply even when there is no load on the output.
Dropout Voltage:
- The dropout voltage (VDROPOUT) is the minimum difference between VIN and VOUT required to maintain regulation.
- It is typically 0.3V and can go up to 0.5V depending on the load current.
Shutdown Mode:
- To put the device into shutdown mode, pull the shutdown pin low.
- In shutdown mode, the device draws a very low current (ISD) of 0.1μA to 0.5μA.
Temperature Considerations:
- The device operates over a temperature range of -40°C to 125°C.
- For storage, the temperature range is -65°C to 150°C.
- Ensure proper heat dissipation if the device is operated near its maximum temperature limits.
Thermal Management:
- The thermal resistance (θJA) is 45°C/W, indicating the efficiency of heat transfer from the junction to the ambient environment.
- Use a heatsink or other cooling methods if the device is expected to operate at high power levels or in high-temperature environments.
PCB Layout:
- Follow recommended PCB layout guidelines to ensure optimal performance and thermal management.
- Place the device close to the load to minimize trace resistance and inductance.
Capacitors:
- Use appropriate input and output capacitors as specified in the datasheet to ensure stability and filter out noise.
- Typical values for input and output capacitors are provided in the datasheet.
Protection:
- The device includes built-in protection features such as overcurrent protection and thermal shutdown.
- Ensure that these features are not triggered by excessive load or environmental conditions.
