Figure 30 shows a sample component placement and
routing for the typical application shown in Figure 31.
NOTES:
1. Layout scale is approximate; routing lines are just for illustration
purposes; they do not necessarily conform to normal PCB
design rules. High current buses are wider, shown with parallel
lines.
2. Approximate size of the above layout is 1.6 x 0.6 inches; almost
half of the area is just the FET (D2PAK or similar SMD-220
package).
3. R1 sense resistor is size 2512; all other R’s and C’s shown are
0805; they can all potentially use smaller footprints, if desired.
4. The RL and CL are not shown on the layout.
5. R4 uses a via to connect to GND on the bottom of the board; all
other routing can be on top level. (It’s even possible to eliminate
the via, for an all top-level route).
6. PWRGD signal is not used here.
