The cxsu6358 is a synchronous boost chip, which is mainly used in battery powered portable devices. The power MOS is integrated inside, and the external application circuit is very simple.
Cxsu6358 has built-in output short-circuit protection. After the output short-circuit, the IC will cut off the battery and output, wait for 120ms, and then re detect the output state. If the output short-circuit state is removed, the chip will automatically return to normal operation, if the short-circuit state is still
If yes, it will be detected every 120ms until the output short circuit state is removed.
The cxsu6358 is PWM working mode, working frequency is 550kHz, and the maximum output current is 2.1a at 5V output. When the output is light load, the cxsu6358 works in burping mode to reduce battery loss.

The cxsu6358 is a synchronous boost chip, which is mainly used in battery powered portable devices. The power MOS is integrated inside, and the external application circuit is very simple.
