... Overload Protection (OLP), Over-Voltage Protection (OVP), Abnormal Over- Current Protection (AOCP) and Line Under-Voltage Protection (LUVP). During startup, the FSL206MR offers good soft-start performance. The internal high-voltage startup switch and the burst- mode operation with very low operating current reduce the power loss in standby mode ...
