Cxsd6167 cxsd6167a cxsd6167b is a wide input range, high efficiency CC / CV function of voltage reduction chip, which can be CV (constant voltage) output or CC (constant current) output. Cxsd6167 cxsd6167a cxsd6167b can provide 3A output current at a switch frequency of up to 230khz.
Cxsd6167 cxsd6167a cxsd6167b does not need to use high-cost precision current sampling resistor, which is very suitable for battery and adapter applications with precise constant current requirements. The cxsd6167 cxsd6167a cxsd6167b has a higher conversion efficiency than the traditional constant current switching regulator by eliminating the current sampling resistance that generates power consumption. The protection features include cycle by cycle current limiting, thermal shutdown and short-circuit frequency return. The chip provides sop8-ep package, which only needs very few peripheral devices.
