6 / 9 page FIXED FREQUENCY WHITE LED DRIVER FSP3301 2007-4-16 6/9 If the PWM signal is above 1 KHz, dimming can be achieved by using the circuit shown in Figure 7 Figure 7 Dimming Control Using a Filtered PWM Signal Open Load Protection Open Load protection will hold the output voltage equal Vov if an over-voltage condition is present due to an open circuit condition when the OV pin is tied to the output. In some cases an LED may fail, this will result in the feedback voltage always being zero. Figure 8 shows the behavior of the FSP3301 into an open load. Figure 8 Startup Waveforms into an Open Load Layout Considerations Careful attention must be paid to the PCB board layout and component placement. Proper layout of the high frequency switching path is critical to prevent noise and electromagnetic interference problems. Due to the high frequency switching the length and area of all the traces connected to the switch node should be minimized. |
