Instructions for Use
Power Supply Connection:
- Connect the input voltage (VIN) to Pin 1.
- Connect the ground (GND) to Pin 8.
Output Configuration:
- Connect the output capacitor (COUT) between Pin 5 (VOUT) and Pin 8 (GND).
- The output voltage will be the inverted value of the input voltage.
Input Capacitor:
- Place an input capacitor (CIN) between Pin 1 (VIN) and Pin 8 (GND) to stabilize the input voltage.
Oscillator Components:
- Connect an external resistor (R) between Pin 6 (OSC) and Pin 8 (GND) to set the operating frequency.
- Connect an external capacitor (C) between Pin 7 (OSC) and Pin 8 (GND) to set the operating frequency.
Shutdown Mode:
- To enable shutdown mode, connect Pin 4 (SHDN) to GND (Pin 8). This will reduce the current consumption to less than 1μA.
- To resume operation, disconnect Pin 4 (SHDN) from GND or apply a high logic level to this pin.
Layout Considerations:
- Keep the layout compact to minimize parasitic inductance and capacitance.
- Use short, wide traces for power and ground connections to reduce resistance and inductance.
Component Selection:
- Choose capacitors with low ESR (Equivalent Series Resistance) for better performance.
- Ensure the inductor and capacitors are rated for the maximum expected current and voltage.
Thermal Management:
- Ensure adequate heat dissipation if operating at high currents or in high ambient temperatures.
- Consider using a heatsink or thermal pad if necessary.
Testing:
- Measure the input and output voltages to ensure correct operation.
- Check the quiescent current and efficiency under different load conditions.
Safety Precautions:
- Ensure all components are rated for the expected voltages and currents.
- Follow standard safety guidelines when handling and testing electrical circuits.
