Voltage Regulators AN8029 Self-excited RCC pseudo-resonance type AC-DC switching power supply control IC s Overview The AN8029 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-period can be set separately by using the external capacitor and resistor respectively.

It is suitable for the power supply of AV eq
