Board Layout Suggestions
When laying out the printed circuit board, the following check-
list should be used to ensure proper operation of the ADP3801
and ADP3802. These items are also illustrated graphically in
the layout diagram on the evaluation board application note.
Check the following in your layout:
1) The IC ground must return to a) the power and b) the signal
grounds with as short of leads as possible. If a double layer
PCB board is used and a ground plane is available, connect
all grounded parts directly to the ground plane. The ground
returns to the anode of the Schottky diode and the minus
terminal of C
IN
should have as short of lead lengths as possible.
2) Connect the IC’s current sense pins (CS+ and CS–) to R
CS
with as short of leads (<0.5 inch) as possible.
3) Route the CS+ and CS– traces together with minimum spac-
ing. The filter capacitors should be close to the IC.
4) Connect the positive side of C
IN
as close as possible to the
source of the P-channel MOSFET (or the emitter of the
PNP). This capacitor provides the ac current to the pass
transistor.
5) Connect the input decoupling capacitor (0.l
μ
F) close to the
VCC input of the IC. This capacitor carries the DRV peak
currents.
6) Connect the 0.1
μ
F LDO decoupling capacitor as close as
possible to the VL pin.
7) The
RESET
pin has an internal pull-up, and should be pulled
low with an external resistor. The
RESET
pin is high imped-
ance and should not be allowed to float.
