1 VO = 12/5 of the applied reference voltage 1% typical. Minimum VPLUS voltage for regulation depends on the external transistor Vbe and the shunt voltage.  
2 VO = 12/5 of the applied reference voltage 2% typical. Minimum VPLUS voltage for regulation depends on the external transistor Vbe and the shunt voltage.  
3 The maximum output current level is set by the selection of the current shunt and power transistor.  
4 (VSENSE – 5 V Reference) The latch-off level is determined by the output level of the sense amplifier. When the amplifier output approaches 5 V, the output is latched off.  
This allows the maximum current output level to be determined by the shunt resistor value. Latch-off can be restored to on by cycling the PWM input off and back on.  
5 Internal delay only. The external delay depends on the external capacitor values, LED string impedance, and wiring inductance.  
6 This specifies VPLUS only—ground current includes external transistor base drive.
