NOTES:
1. Layout scale is approximate; routing lines are just for illustration
2. Approximate size of the above layout is 1.6 x 0.6 inches; almost
3. R1 sense resistor is size 2512; all other R’s and C’s shown are
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
6. PWRGD signal is not used here.

purposes; they do not necessarily conform to normal PCB
design rules. High current buses are wider, shown with parallel
lines.
half of the area is just the FET (D2PAK or similar SMD-220
package).

other routing can be on top level. (It’s even possible to eliminate
the via, for an all top-level route).
