Maxim Integrated ICL7662MJA Voltage Converter

The ICL7662MJA from Maxim Integrated is a highly versatile, monolithic CMOS voltage converter that offers reliable performance for a wide range of applications. As a charge pump voltage inverter, it is adept at converting a positive voltage in the range of 1.5V to 12V to the corresponding negative voltage, making it an ideal choice for battery-powered devices, portable instruments, and any application requiring an efficient negative power supply.

Encased in a durable CDIP package, the ICL7662MJA ensures a robust construction that stands up to demanding conditions. Its design is optimized for ease of use, requiring only two external non-critical capacitors to complete the voltage conversion function. This simplicity allows designers to implement a negative supply where needed with minimal design effort and board space.

With a high power efficiency, the ICL7662MJA is capable of delivering up to 20mA with a typical voltage conversion efficiency of 99.9% at no load, and 97% under full load conditions. This efficiency, combined with its no-load quiescent current of just 2mA, makes it an energy-conscious choice for extending battery life in portable devices.

Furthermore, the ICL7662MJA features a frequency operation of 10kHz, which strikes a balance between small capacitor size and low output ripple, ensuring a stable and clean negative voltage output. This is particularly advantageous in applications such as op-amp power supplies, memory bias generators, and data acquisition systems, where maintaining signal integrity is of paramount importance.

Maxim Integrated's commitment to quality is evident in the ICL7662MJA's design, which includes over-temperature and short-circuit protection, safeguarding your circuitry from potential damage due to abnormal operating conditions. The device's reliability and longevity are further enhanced by its wide operating temperature range, making it suitable for industrial-grade applications.

In summary, the ICL7662MJA from Maxim Integrated is a compact, efficient, and reliable solution for generating a negative voltage rail, providing designers with a simple-to-use, high-performance option for a multitude of electronic applications.
