Microchip TC7660CPA DC-DC Charge Pump Voltage Converter DIP-8 20mA

Microchip TC7660CPA DC-DC Charge Pump Voltage Converter converts a positive input voltage of 1.5 V to 10 V into a corresponding negative output voltage of -1.5 V to -10 V, in a standard 8-pin DIP package.

The TC7660CPA is a DC-to-DC charge pump voltage converter designed for power management in electronic circuits. Its charge pump operation removes the need for bulky inductors, which helps reduce overall component size and minimise electromagnetic interference (EMI), a consideration for noise-sensitive applications. Only two external capacitors are required to complete the circuit, making it straightforward to use for inverting power supply generation.

Key Features

• Pin-compatible with the 7660 charge pump voltage converter, allowing a direct drop-in replacement
• Current consumption of 80µA at a 5 V input, suited to battery-powered equipment
• 3kV HBM (Human Body Model) ESD protection
• On-board oscillator with a nominal frequency of 10kHz
• An external capacitor can be connected from the OSC pin to ground for operation below 10kHz
• No external diode required for high-voltage operation
• Housed in a standard 8-pin DIP (Dual In-line Package) for prototyping and through-hole mounting

Performance

The converter is specified with 99.9% voltage conversion efficiency and up to 98% power efficiency, which supports minimal energy waste in portable devices. The operating temperature range is 0°C to 70°C.
