LTC1046IN8 - High Efficiency Inverting Voltage Converter

The LTC1046IN8 is a high-performance, inverting voltage converter designed by Linear Technology, renowned for its expertise in the field of power management integrated circuits. This device is specifically engineered to provide a simple and efficient solution for applications requiring a negative voltage derived from a positive input voltage. It is an ideal choice for a wide range of electronic applications, from portable devices to industrial systems, where space and efficiency are critical considerations.

Featuring a unique charge pump design, the LTC1046IN8 is capable of delivering an inverting output voltage which is almost equal to the negative of the input voltage, with a high level of efficiency that is not possible with linear regulators. This makes it an excellent choice for battery-powered applications where extending battery life is paramount. The converter operates over a wide input voltage range from 1.5V to 10V, making it versatile for various power sources.

The LTC1046IN8 is housed in a compact 8-pin PDIP (Plastic Dual In-line Package), which is designed for easy integration into a multitude of circuit designs. Its small footprint allows designers to save valuable board space without compromising on performance. Additionally, the device requires only two external capacitors for the voltage conversion process, further simplifying the design and reducing external component count.

Key features of the LTC1046IN8 include low quiescent current, typically 120μA, which contributes to its high efficiency and makes it suitable for always-on and standby applications. The device also offers a low voltage loss feature, with a typical voltage drop of only 1.1V at no load, ensuring that the output voltage remains close to the desired level even when the input voltage varies or the load changes.

In summary, the LTC1046IN8 from Linear Technology is a robust and efficient inverting voltage converter that offers ease of use, minimal external components, and a compact package. It is an excellent choice for designers looking to implement a negative voltage supply with high efficiency and reliability.
