Applications Information
TABLE 1. RECOMMENDED COMPONENTS (Continued)
The EL7520 and EL7520A provide a multiple output power
supply solution for TFT-LCD applications. The system
consists of a high efficiency boost controller and three low
cost linear-regulator controllers (V ON , V OFF , and V LOGIC ).
The block diagram of the whole part is shown in Figure 24.
Table 1 lists the recommended components.
