April 2020，NuVolta（shanghai）launches first charge pump chip NU2105. NU2105 has small chip area and high efficiency. The FOM index of loss area product is only 5.91, which is currently ahead of the industry standard.

NU2105 is a 97.5% efficient, 8-A battery charging solution using a switched cap architecture. This architecture and the integrated FETs are optimized to enable a 50% duty cycle, allowing the cable current to be half the current delivered to the battery, reducing the losses over the charging cable as well as limiting the temperature rise in the application. Compared with the low-voltage direct charging solution, the cost of wires and interfaces is greatly reduced.

High efficiency and low temperature rise meet the needs of charge pump high current operation. NU2105 at 2:1 charge mode, two chips are charged in parallel with 8A current, and the maximum temperature is 40.5℃; one chip runs 6A current charging, the maximum temperature is about 42.7℃.

NU2105 integrates Programmable Protection Features, including input over-voltage protection、input over-current protection with adjustable alarm、input over-voltage with external OVP FET、battery over-voltage protection with adjustable alarm、output over-voltage protection、input over-current protection with adjustable alarm、IBAT over-current protection with adjustable alarm、battery temperature monitoring、connector temperature monitoring and so on, which is very suitable for use in digital products such as mobile phones and tablets.
