The TC660EOA is a CMOS charge pump voltage converter. It's designed to efficiently invert or double an input voltage with minimal external components. This device is commonly used to generate a negative voltage from a positive supply, making it useful in applications requiring both positive and negative rails.

Applications:

• Generating negative supplies for op-amps
• LCD bias
• Memory programming voltage
• Data acquisition systems
• Portable electronic devices

Features:

• CMOS charge pump technology
• Voltage inversion and doubling
• High power conversion efficiency
• Low quiescent current
• Requires only two external capacitors
• Small outline package

Benefits:

• Provides a simple and efficient way to generate a negative voltage.
• Reduces component count and board space requirements.
• Extends battery life in portable applications due to low quiescent current.
• Offers reliable performance in a wide range of operating conditions.
• Simplifies power supply design.

Technical Specifications:

The TC660EOA typically operates from a supply voltage of 1.5V to 5.5V. The output voltage is approximately the inverse of the input voltage (or twice the input voltage in doubling mode), with some voltage drop due to internal resistance. The output current capability depends on the input voltage and switching frequency. Consult the datasheet for specific values. The switching frequency is typically in the kHz range.
