Product Description
Microchip TC962CPA Charge Pump Regulator is an enhanced DC-to-DC converter that operates as a high-voltage inverter. It provides reliable 18V output voltage with an output current capacity of 80 mA and a switching frequency of 24 kHz. Packaged in a PDIP 8-Pin through-hole mount, this device is designed using CMOS technology to achieve superior voltage conversion efficiency of 99.9% and power conversion efficiency of 97%.
The TC962CPA improves on the classic 7662 design by eliminating the low-voltage terminal, simplifying circuit design and reducing component requirements. The device functions well over a wide input voltage range of 3V to 18V and can operate at temperatures from -55°C up to 125°C, suitable for demanding industrial and electronic environments.
Its low output impedance (approximately 28 ohms with proper capacitors) ensures minimal voltage loss, making it effective in power-sensitive applications. The pin compatibility with TC7662, ICL7662, and SI7661 ensures easy upgrade or replacement.
Operational flexibility is enhanced via an oscillator frequency doubling option by grounding pin 6, reducing the size of external capacitors. Enhanced 80 mA output current compared to standard devices. Wide input voltage range from 3V to 18V.
No external diodes needed due to built-in design improvements. Low output impedance ensures high efficiency in voltage regulation. Operating temperature range from -55°C to 125°C suitable for harsh conditions. Oscillator frequency doubling option for component size reduction.
Pin compatible with popular related devices (TC7662, ICL7662, SI7661).
This charge pump regulator finds applications in industrial electronics, laboratory equipment, power management circuits, and embedded systems requiring efficient voltage inversion or regulation.
