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. Adjustable minimum frequency or maximum duty factor limit. Adjustable overcurrent protection limit. Supply voltage out-of-range protection. Slow-start facility. QUICK REFERENCE DATA Supply voltage Supply current Output pulse repetition frequency range Output current LOW Operating ambient temperature range PACKAGE OUTLINE 9-lead SIL; plastic (SOT-110B); SOT110-1; 1996 November 18.
