TK75001 OFF-LINE APPLICATION EXAMPLE
Figure 8 shows an off-line, universal input, 12 W power supply. The TK75001 is the controller IC for a flyback converter
with self-bias and constant-frequency, current-mode control. The TK75001 drives the MOSFET directly to switch the
flyback transformer. Feedback is accomplished by means of a TL431, configured as a secondary side error amplifier and
voltage reference, driving an opto-coupler for isolation.
