LTC1682IMS8-5: High-Efficiency, Low-Noise Doubler Charge Pump

The LTC1682IMS8-5, manufactured by Linear Technology, is a high-performance, low-noise, switched-capacitor voltage doubler. It is designed specifically to provide a regulated output voltage that is twice the input voltage, making it an ideal component for applications requiring a small, efficient power supply solution. This product stands out for its ability to maintain a low-noise output, which is crucial in sensitive electronic applications.

Encased in an MSOP-8 package, the LTC1682IMS8-5 offers a compact form factor that is suitable for space-constrained designs. It operates over a wide input voltage range from 2.7V to 4.5V, which allows for flexibility in various battery-operated and portable devices. The device's regulated output voltage of 5V ensures consistent performance for circuits that demand a stable voltage supply.

One of the key features of the LTC1682IMS8-5 is its high conversion efficiency. The integrated low-dropout (LDO) regulator allows for efficient operation, even at higher input voltages, by reducing power loss. This efficiency is further enhanced by its low quiescent current, making it an energy-saving choice for battery-powered applications.

The LTC1682IMS8-5 also incorporates a low-noise charge pump technology. This technology minimizes the output voltage ripple, which is essential for maintaining signal integrity in noise-sensitive applications such as RF circuits or high-precision analog systems. Additionally, the device includes built-in soft-start circuitry that gradually increases the output voltage, preventing inrush current and reducing stress on the power supply during startup.

For protection and reliability, the LTC1682IMS8-5 features over-temperature and short-circuit protection. These safeguards help to ensure the longevity and stable operation of the device under various conditions. The product is also designed to meet the rigorous standards of the industrial temperature range, making it suitable for a wide range of environments.

In summary, the LTC1682IMS8-5 from Linear Technology is a versatile, high-efficiency voltage doubler that offers low noise, compact packaging, and robust protection features. It is an excellent choice for designers looking to enhance the performance of their power supply circuits in portable, battery-operated, and noise-sensitive electronic devices.
