The adapted commercial power grid AC voltage range of switch power supply which is composed of TEA1533 is 70~276V, on the waiting state, the power consumption is lower than 3W. TEA1533 has complete protection circuit, it includes: demagnetization protection, over-current protection, over-voltage protection, switch transformer winding short circuit protection, under-voltage protection, chip overheat protection and the safe soft-start circuit(decreasing output power) after the protection action, according to the commercial power grid rectified voltage, it can determine the IC's start voltage. TEA1533 also has the characteristics of soft-start .
