    ... Under operating CP charge (under error mode) analog dimming and burst dimming are not operate. 10. Under operating Slow Start Control (SS is less than 1.5V), It does not operate Timer Latch. 11. By STB voltage, BD9215F, BD9215FV are changed to 2 states. Therefore, do not input STB pin voltage between one state and the other state (0.8~2.0V). ...
