Maxim Integrated's MAX680CSA+T - Charge Pump Voltage Converter

The MAX680CSA+T is a highly efficient, CMOS charge-pump voltage converter manufactured by Maxim Integrated. This device is engineered to deliver a dual output from a single positive input voltage, which makes it an ideal choice for applications that require both positive and negative regulated voltages. The MAX680CSA+T is perfect for small, battery-operated devices, as well as for systems that benefit from the converter's compact size and high performance.

The converter operates by switching at a frequency of 10kHz to 100kHz, which is selectable by an external capacitor. This feature allows designers to balance between efficiency and external component size. The MAX680CSA+T can generate ±10V outputs from a +5V input, ±12V outputs from a +5V to +6V input, or can double a +4.5V to +5.5V input.

The versatility of the MAX680CSA+T is one of its key advantages. It comes in a small 8-pin SO package, making it suitable for space-constrained applications. Moreover, its high efficiency minimizes the need for heat sinking, thus reducing the overall design footprint and cost.

Key features of the MAX680CSA+T include:

• Low power operation with quiescent current of 100µA
• High efficiency with a power efficiency up to 98%
• Wide operating voltage range, typically from 4.5V to 5.5V
• Adjustable switching frequency for design flexibility
• Thermal overload protection to ensure device safety
• Low-noise operation suitable for sensitive analog circuits

In summary, the MAX680CSA+T is a reliable and versatile voltage converter that offers a compact solution for generating dual output voltages. With its low power consumption, high efficiency, and design flexibility, it is well-suited for a wide range of applications, including portable devices, data acquisition systems, and operational amplifier power supplies. Maxim Integrated's reputation for quality and performance makes the MAX680CSA+T a trustworthy component for designers looking to optimize their power management solutions.
