LED 1 Cathode Connection. Current flowing into LED1 is 270/250 times the current
flowing into SET. LED1 is high impedance when EN is low.
LED 2 Cathode Connection. Current flowing into LED1 is 270/250 times the current
flowing into SET. LED2 is high impedance when EN is low.
LED 3 Cathode Connection. Current flowing into LED1 is 270/250 times the current
flowing into SET. LED3 is high impedance when EN is low.
LED 4 Cathode Connection. Current flowing into LED1 is 270/250 times the current
flowing into SET. LED4 is high impedance when EN is low.
Ground
Power supply
Enables PN6316A/B signal , H: Ative , L : Power Down .
VSET terminal is used to connect an external resistor to set output current.
The current flowing into VSET sets the bias current into
each LED by ILED_= 250 x ISET.
VSET is internally biased to 0.306V. VSET is high impedance when EN is low.
