Table 3. Surface-Mount Components

(See Figure 1 for schematic and Table 4 for manufacturers' telephone numbers.)

Note 1: Four IRF7101s total; each device has both sections connected in parallel.

Note 2: These transformers have different sizes and pinouts. The MAX783 EV kit has the correct pad layout for the TTI5902 trans-

former, but all the transformers listed can be wired in easily.
