IC power supply controller TC7738WBG

TC7738WBG is a system power IC which builds in 6 channels of a buck DC-DC convertor and 2 channels of LDO. The IC operation voltage(3.3 V or 5 V) can be changed using I2 C interface and pin settings, power supply can be provided to various systems. In addition, this product incorporates the PROTECTION-SW for the input protection.
