LTC1682CMS8-3.3: High Efficiency, Low Noise Doubler Charge Pump

The LTC1682CMS8-3.3 is a versatile and efficient integrated circuit from Linear Technology, designed to serve as a high-efficiency, low-noise doubler charge pump. This product is specifically engineered to generate a regulated output voltage which is twice the input voltage, delivering a fixed 3.3V from an input ranging from 2.7V to 4.5V. The LTC1682CMS8-3.3 is housed in a compact MSOP-8 package, making it suitable for space-constrained applications.

One of the key features of the LTC1682CMS8-3.3 is its high conversion efficiency, which can reach up to 96%. This is achieved through its low quiescent current and the use of low-loss Schottky diodes in the charge pump circuit. The device also boasts a low noise operation, thanks to its constant-frequency, voltage-doubler architecture, which reduces output voltage ripple and minimizes interference with RF and sensitive analog circuits.

The LTC1682CMS8-3.3 is equipped with a low external parts count requirement, needing only two small ceramic capacitors for the charge pump. This simplicity in design translates to a reduced bill of materials and ease of implementation in a wide range of applications, including handheld devices, GPS units, and portable communication devices.

Safety and reliability are also focal points for this product. The LTC1682CMS8-3.3 includes built-in thermal shutdown and current limit features to protect the device and the application circuit from adverse conditions. Furthermore, the device operates over a wide temperature range, making it suitable for use in various environments.

For designers looking for a reliable and efficient voltage doubling solution, the LTC1682CMS8-3.3 is an excellent choice. Its high efficiency, low noise performance, and ease of use, combined with robust protection features, make it a preferred component for powering complex electronic systems.

In summary, the LTC1682CMS8-3.3 from Linear Technology is a high-performance, regulated charge pump voltage doubler. Its compact size, high efficiency, and low noise operation make it an ideal choice for portable and noise-sensitive applications that require a stable 3.3V supply from a lower voltage source.
