LTC1144CN8#PBF - High Efficiency Inverting Charge Pump

The LTC1144CN8#PBF is a high-efficiency, inverting charge pump voltage converter designed and manufactured by Linear Technology. It is a versatile component that is well-suited for applications requiring a negative voltage generated from a positive input voltage. The device is capable of providing an output voltage equal to the negative of the input voltage while delivering up to 10mA of output current with greater than 99% efficiency at full load.

This charge pump uses a switched-capacitor technique to achieve its high efficiency, and it operates over a wide input voltage range of 1.5V to 10V. This feature makes it ideal for battery-powered devices where power efficiency is crucial. The LTC1144CN8#PBF is also noted for its low quiescent current, which helps in extending battery life in portable applications.

The LTC1144CN8#PBF is housed in an 8-lead PDIP (Plastic Dual In-line Package) with the product code suffix #PBF indicating lead-free, RoHS-compliant packaging. This makes it suitable for use in environmentally sensitive applications and in jurisdictions with strict regulations on the use of hazardous substances in electronic components.
