Control circuit for switched-mode power supply
GENERAL DESCRIPTION
TEA1039
The TEA1039 is a bipolar integrated circuit intended for the control of a switched-mode power supply. Together with an external error amplifier and a voltage regulator (e.g. a regulator diode) it forms a complete control system. The circuit is capable of directly driving the SMPS power transistor in small SMPS systems. It has the following features: • Suited for frequency and duty factor regulation. • Suited for flyback converters and forward converters. • Wide frequency range. • Adjustable input sensitivity.
