Microchip Technology TC7662BCOA Charge Pump Voltage Converter
The TC7662BCOA is a high-performance, static CMOS charge pump voltage converter manufactured by Microchip Technology. This versatile integrated circuit is designed to provide a reliable solution for applications requiring voltage inversion or voltage doubling with minimal external components. The device is capable of delivering an output current of up to 20mA with a voltage conversion efficiency that remains high even at low voltage levels.
The TC7662BCOA operates over a wide input voltage range from 1.5V to 10V, making it suitable for battery-operated devices as well as for fixed 3.3V, 5V, or 9V power supply systems. Its oscillator frequency of 12kHz ensures low output ripple and a quiet operation, which is crucial for noise-sensitive applications like audio or precision measurement devices.
This voltage converter comes in an 8-pin SOIC package, providing a compact footprint for space-constrained applications. It is designed with several features to ensure reliable operation, including thermal shutdown and overcurrent protection. These features protect the device and the application circuit from potential damage due to abnormal operating conditions.
One of the key advantages of the TC7662BCOA is its ease of use. With only two external capacitors required for the voltage doubling function and one additional diode for voltage inversion, the circuit design is greatly simplified. This simplicity, combined with the converter's high efficiency, makes it an excellent choice for portable devices, where power conservation and space are critical factors.
Applications for the TC7662BCOA are diverse and include LCD bias supplies, op-amp power supplies, memory backup power supplies, and isolated power supplies. Its robustness and versatility make it an ideal choice for designers looking to integrate a reliable power management solution into their products.
Overall, the Microchip Technology TC7662BCOA is a testament to the company's commitment to providing high-quality, innovative solutions for power management challenges across a wide range of electronic applications.
