... A high-level of integration provides a cost-effective power supply requiring only a few external components. The TEA1541 controller enables easy design of highly efficient, reliable switched mode power supplies. Its internal oscillator can be synchronized to pulses from an external signal source. External synchronizing pulses whose frequency is above the SMPS switching frequency range are divided by an internal divider ...

... FUNCTIONAL DESCRIPTION The TEA1541 is intended as the controller for a compact flyback converter for CRT monitor applications. The IC is situated on the primary side of the output transformer. Output power is determined by the current in the primary winding. The voltage across an auxiliary winding in the transformer is converted to a current by resistor R used by the IC to derive the current in the primary winding ...

... VIN enter the safe restart mode. 6.7 Overvoltage protection The TEA1541 allows OVP to be set accurately. The flyback converter output voltage is accurately represented by the voltage across the auxiliary winding. The auxiliary winding voltage is monitored by the current flowing into pin DEM during the demagnetizing cycle of the transformer ...
