ds3994应用电路 application with a single lamp per channel

in this application the internal dc bias voltage at the lcm and ovd pins allows for an ac-coupled input. this design can make the external circuitry very simple. a typical operating circuit for this application is shown in figure 1.figure 1. typical operating circuit with a single lamp per channel.in this application, the thresholds are referenced to v_dcb. the values are listed in table 2 and may be different for other parts.table 2. ds3994 lcm and ovd thresholds (for figure 1)parametersymbolmintypmaxunitslamp off thresholdv_lot0.300.400.50vlamp overcurrent thresholdv_loc1.802.002.20vlamp regulation thresholdv_lrt0.941.001.06vovd thresholdv_ovdt0.901.001.10v
