Introducing the LTC1045CN: A High-Efficiency CMOS Switched-Capacitor Voltage Converter

The LTC1045CN is a versatile switched-capacitor voltage converter designed by Linear Technology, now part of Analog Devices. This innovative component is built using CMOS technology, which ensures a high level of integration and energy efficiency, making it an excellent choice for a variety of applications where power management is critical.

The LTC1045CN is capable of voltage doubling, voltage inversion, and fractional conversion (fractional increase or decrease) without the need for any external diode or inductor. Its internal circuitry includes four low on-resistance switches, which are used to rearrange the connections to an external capacitor, providing the desired voltage conversion.

One of the key features of the LTC1045CN is its high-frequency operation, which allows the use of small external capacitors. This high switching frequency, combined with the low power consumption of the CMOS process, results in a compact and power-efficient solution that is particularly suitable for battery-powered devices. The device can operate over a supply voltage range of 1.5V to 10V, making it flexible for use with various power sources.

With its no-load quiescent current of just 100µA and an operating current of 10mA, the LTC1045CN is optimized for low-power applications. Its power efficiency is further enhanced by the low voltage drop across the internal switches, typically just 0.5V at 10mA load.

The LTC1045CN comes in a narrow 16-pin DIP package, which is easy to integrate into a wide range of electronic systems. Its robust design ensures reliable operation over an extended temperature range, making it suitable for industrial and automotive applications as well as consumer electronics.

Whether you're designing a portable device, a power backup system, or any other power-sensitive application, the LTC1045CN offers a high-efficiency solution for your voltage conversion needs. Its ease of use, combined with the reputation of Linear Technology for high-quality, reliable components, makes the LTC1045CN a smart choice for your next project.
