The ICL7660IJA from Maxim Integrated is a highly efficient, monolithic, CMOS voltage converter that offers a simple solution for generating a negative voltage from a positive voltage input. This versatile device is designed to meet the needs of a wide range of applications, including battery-powered devices, and portable consumer electronics, where extending battery life is of paramount importance.
Operating over a voltage range of 1.5V to 10V, the ICL7660IJA can deliver an output voltage equal to the negative of the input voltage, making it ideal for applications that require a dual supply from a single battery source. Its no-load quiescent current is extremely low, typically 1.5µA, which helps in maintaining the efficiency of the overall system and prolonging battery life.
The ICL7660IJA is designed with a frequency boost pin that allows users to increase the oscillator frequency, thereby reducing the output impedance and allowing for smaller external capacitors. This feature is particularly useful in space-constrained applications where component size is critical. Furthermore, the device also includes an oscillator control pin that can be used to shut down the ICL7660IJA, reducing the supply current to a 20nA trickle, which is beneficial in power-sensitive designs.
This voltage converter is available in an 8-pin CerDIP package, ensuring robustness and reliability for industrial-grade applications. Its operating temperature range of -40°C to +85°C allows the device to perform consistently in a variety of environmental conditions.
The ICL7660IJA by Maxim Integrated is a testament to the company's commitment to providing innovative, high-performance power solutions. Its ease of use, combined with its power-saving features, make it an excellent choice for designers looking to implement efficient voltage conversion in their products.
