TEA1501

The TEA1501 (Greeny) is the low power member of the GreenChipä family and is especially designed for standby switched mode power supply applications. Greeny incorporates all the necessary functions for an efficient and low cost power supply for 90 to 276 V AC universal input. Greeny is a monolithic integrated circuit and is available in a DIP8 package. The design is made in the BCD_PowerLogic750 process and includes the high voltage switching device. Using only 7 functional pins, Greeny contains extensive control functions to form a flexible and a reliable power supply with a minimum of external components. Greeny operates in a flyback topology (see Fig.1) with a fixed switching frequency, constant primary peak current control and regulates the output voltage in burst mode.

Applications include low power supplies and standby power supplies as used in television, monitor, lighting electronics and domestic appliances with an output power from 0.1 to 3 W.
