Built-in double N-type low impedance power switch tube, the conversion efficiency is as high as 95.6% when
24V input and 9V3A output.
CX8831CB has an input working voltage of up to 36V and an output voltage range of 3.3V to 21V, which can
provide a maximum output power of 45W. The output voltage and current are adjusted according to the
identified fast charging protocol.
CX8831CB can adapt the input voltage and automatically adjust the output power according to the input voltage.
The output of CX8831CB has CV/CC characteristics. When the output current is less than the set value, the CV
mode is output and the output voltage is constant. When the output current is greater than the set value, the
CC mode is output and the output voltage is reduced.
