Working Principles

The TC962COE operates by utilizing an internal charge pump circuit to generate a negative output voltage from a positive input voltage. When the EN pin is high, the charge pump circuit charges a capacitor during the positive half-cycle of the input voltage. During the negative half-cycle, the charge stored in the capacitor is transferred to the output, resulting in a negative voltage.

The TC962COE can be used in various applications that require a negative voltage supply. Some potential application fields include:

1. Portable electronic devices: The TC962COE can be used to generate a negative voltage for LCD displays, backlighting systems, or audio amplifiers in portable devices such as smartphones, tablets, and portable media players.

2. Industrial equipment: It can be employed in industrial control systems, where a negative voltage is required for powering analog sensors, actuators, or communication modules.

3. Automotive electronics: The TC962COE can find applications in automotive electronics, such as powering LED lighting systems, audio amplifiers, or sensor interfaces.

4. Medical devices: It can be utilized in medical equipment that requires a negative voltage supply, such as patient monitoring systems or portable medical devices.
