Power
Supply
Requirements
General requirements:
•
+5
VDC
± 0.25V @ 2.0 amps
•
+12
VDC
±
O.5V
@ 1.0
amp
CAUTION
Regarding
switching
power
supplies:
Tetris
uses much less current from the
5V
power
supply
than
most
video games.
Not all switching power supplies will stay
in
regulation with such a low current (ap-
proximately
1 amp). Before plugging in
the
Tetris game PCB, make sure
your
switching power supply will stay
in
regu-
1ation
with only a 1 amp load. Otherwise,
the
switcher
may
produce
a
voltage
greater than
5V
and
seriously damage
the game
PCB.
