PU
LED1 (Pin 18):
First Input of Current Mirror for an LED
String. Connect the negative end of first string of LEDs to
this pin. If not in use, leave floating.
SW4 (Pin 19):
Switch Pin for LED Switcher. This is the
collector of an internal NPN power switch. Minimize the
metal trace area connected to this pin to minimize EMI.
SW1 (Pin 20):
Switch Pin for AV
DD
Switcher. This is the
collector of an internal NPN Power switch. Minimize the
metal trace area connected to this pin to minimize EMI.
PGND14 (Pin 21):
Power Ground for LED Switcher and
AV
DD
Switcher. Tie directly to local ground plane.
V
CC
(Pin 22):
Input Supply. Must be locally bypassed.
D2 (Pin 23):
Anode Connection of Internal Schottky Diode
for V
OFF
Switcher.
SW2 (Pin 24):
Switch Pin for V
OFF
Switcher. This is the
collector of an internal NPN Power switch. Minimize the
metal trace area connected to this pin to minimize EMI.
SGND (Pin 25):
Signal Ground. This is the Exposed Pad,
which must be soldered directly to a local ground plane to
achieve optimum thermal performance.
