Product data sheet

1. General description

The TEA1501 is the low power member of the GreenChip family and is especially

designed for standby Switched Mode Power Supply (SMPS) applications. The TEA1501

incorporates all the necessary functions for an efficient and low cost power supply for 90 V

to 276 V AC universal input. The TEA1501 is a monolithic integrated circuit and is

available in a SO8 package. The design is made in the BCD_PowerLogic750 process and

includes the high voltage switching device. Using only seven functional pins, the TEA1501

contains extensive control functions to form a flexible and a reliable power supply with a

minimum of external components. The TEA1501 operates in a flyback topology (see

Figure 3) with a fixed switching frequency, constant primary peak current control and

regulates the output voltage in Burst mode.

Applications include low power and standby power supplies as used in television, monitor,

lighting electronics and domestic appliances with an output power from 0.1 W to 3 W.
