The LM2665M6 is a charge pump voltage converter IC designed to invert input voltages. It comes in a 6-pin surface-mount SOT-23 package. Here is a brief overview of its pin functions:
1. V+ (Pin 1): Positive input voltage. This is the supply voltage pin where the input voltage is applied.
2. GND (Pin 2): Ground. This pin is connected to the ground of the circuit.
3. C1+ (Pin 3): Positive terminal of the external flying capacitor. The flying capacitor is essential for the charge pump operation.
4. C1- (Pin 4): Negative terminal of the external flying capacitor. This pin is connected to the other side of the flying capacitor.
5. VOUT (Pin 5): Output voltage. This pin provides the inverted output voltage.
6. OSC (Pin 6): Oscillator control. If connected to V+, it operates in a normal mode; if connected to ground, it operates in a low power mode.
The LM2665M6 is commonly used in applications where negative voltage needs to be generated from a positive supply, such as in dual-supply operational amplifier circuits.
