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)| Parameter | Symbol | Min | Typ | Max | Units |
| Lamp off threshold | VLOT | 0.30 | 0.40 | 0.50 | V |
| Lamp overcurrent threshold | VLOC | 1.80 | 2.00 | 2.20 | V |
| Lamp regulation threshold | VLRT | 0.94 | 1.00 | 1.06 | V |
| OVD threshold | VOVDT | 0.90 | 1.00 | 1.10 | V |
