Pinout
1. V+: Supply voltage input. Connect to the positive supply voltage.
2. CAP+: Positive terminal for the charge pump capacitor. Connect a capacitor between CAP+ and CAP-.
3. CAP-: Negative terminal for the charge pump capacitor.
4. GND: Ground reference for the IC.
5. OUT: Output voltage pin. It provides the inverted or doubled voltage, depending on the configuration.
6. LV: Logic voltage pin. Used to select low voltage mode for efficient operation at lower input voltages.
7. OSC: Oscillator control. Can be used to adjust the oscillator frequency with an external capacitor or synchronize with an external clock.
8. SD: Shutdown control pin. Pulling this pin low disables the device, reducing power consumption.
The LM2662M can be configured to invert input voltage, effectively producing a negative output voltage from a positive input, or to double the input voltage, depending on configuration and external components.
