AIC1383
PIN DESCRIPTIONS
PIN 1:
PIN 2:
PIN 3:
VIN - 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.
VREF - Reference voltage input. Pull
this pin low to shutdown device.
APPLICATION INFORMATION
Layout Consideration
AIC1383 is in SOP-8 package 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.
PIN 4: VOUT - Output pin.
PIN 5~8: VCNTL - Input supply pin. It is used to
supply all the internal control
circuitry.
The large copper at V_CNTL pins is available, and
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.
