The AN8028 is an IC developed for controlling the self-excited switching power supply employing the RCC pseudo-resonance type control method. It is compact, equipped only with the necessary minimum functions. The maximum on-period and the minimum off-pe- riod can be set separately by using the external capacitor and resistor respectively. It is suitable for the power supply of AV equipment.
