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
collector of an internal NPN Power switch. Minimize the
metal trace area connected to this pin to minimize EMI.
