AIC1383B
PIN DESCRIPTIONS
PIN 1:
- Input supply pin. It provides
main power to create the
external reference voltage by
divider resistors for regulating
V
REF
and V
OUT
.
GND - Ground pin.
VCNTL - Input supply pin. It is used to
supply all the internal control
circuitry.
VIN
PIN 4:
PIN 5:
VREF - Reference voltage input. Pull
this pin low to shutdown device.
VOUT - Output pin.
PIN 2:
PIN 3:
APPLICATION INFORMATION
Layout Consideration
AIC1383B is in SO-8
(DDR1/2)
and
TO-263-5
The large copper at V

the heat dissipation is relieved. Using via to lead
heat into the bottom layer to strengthen as below
figures show.
All capacitors should be placed as close as
possible to relative pins.
resulting in unable to dissipate heat easily when it
operates in high current. In order to prevent
maximum junction temperature exceeded, the
suitable copper area has to use.
