Instructions for Use
NJW1302G
Circuit Configuration:
- Connect the input voltage (VIN) to the VIN pin.
- Connect the output voltage (VOUT) to the VOUT pin.
- Ground the GND pin.
- Connect the FB pin to a voltage divider to set the output voltage.
- Connect the EN pin to a control signal or leave it open for continuous operation.
Capacitors:
- Use a 1μF ceramic capacitor for the input (CIN) and a 1μF ceramic capacitor for the output (COUT).
Inductor:
- Use a 2.2μH inductor for optimal performance.
Thermal Management:
- Ensure adequate heat dissipation by using a PCB with good thermal vias and copper planes.
Layout Considerations:
- Keep the input and output capacitors as close as possible to the IC.
- Minimize the loop area for the high-frequency switching currents.
