Self-excited RCC pseudo-resonance type AC-DC switching power supply control IC

■Overview\nThe 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-period can be set separately by using •Operating supply voltage range:\nStop voltage (8.6 V typical) to 34 V\n•Output block employs the totem pole system.\n•Power MOSFET can be directly driven.\n(output peak current: ±1 A maximum)\n•Small pre-start operating current (95 µA typical) allows using a small size start resistor.\n•Built-in pu;
