Pinout
1. Pin 1 (CAP+): Positive terminal for the external charge pump capacitor.
2. Pin 2 (GND): Ground.
3. Pin 3 (CAP-): Negative terminal for the external charge pump capacitor.
4. Pin 4 (VOUT): Output voltage, which is the inverted input voltage.
5. Pin 5 (LV): Low Voltage Pin; connect to ground for input voltages below 3.5V to improve efficiency.
6. Pin 6 (OSC): Oscillator control; can connect an external capacitor or resistor to adjust the frequency, or it can be left open for standard operation.
7. Pin 7 (V+): Positive supply voltage input.
8. Pin 8 (LV): Duplicate of Pin 5; for additional low voltage mode configuration.
This IC is often used in applications where small size and low power consumption are critical, such as battery-powered devices.
