Cxsd6218 is a composite power management chip, which can provide two low-noise high-speed LDOS and one DC-DC buck with 95% efficiency. Due to the CMOS technology, the working current consumption of the chip is very small, and the low on state resistance is used inside, so that the output capacity of LDO can reach 300mA, and the load capacity of DC-DC can reach 800mA. There are load short circuit protection, temperature protection, over-current protection and other complete protection systems inside, which ensure the safety performance of the chip. The chip adopts dfn3 ?3-10l and other small packages, which is convenient for high-density installation
