Cxsd6105 is a CMOS Buck DC / DC regulator composed of reference voltage source, oscillation circuit, comparator, PWM / PFM control circuit, etc. The PWM / PFM automatic switching control circuit is used to achieve adjustable duty cycle, which has the characteristics of low ripple, high efficiency and large output current in the full input voltage range (2.0-6v). Cxsd6105 has built-in power MOSFET, which uses over-voltage, over-current, over temperature and many other protection circuits. When the control value is exceeded, it will automatically disconnect to protect the chip. This product combines the characteristics of micro encapsulation and low current consumption, and is most suitable for the internal use of power supply of mobile devices
