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 VDCB. The values are listed in Table 2 and may be different for other parts.Table 2. DS3994 LCM and OVD Thresholds (for Figure 1)
