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 fl...
