Light control function (Adj2)
Formula for light control level by light control voltage
ONDuty = (100 - ONDutyMin) * +ONDutyMin (%)
VAdj2 : Adj2 terminal voltage (V)
ONDutyMin = 10 (%)
2.4 - VAdj2
Fig.4 shows the connections of Adj2 terminal.
When the light control voltage is 2.4V or more,
divided voltage by the resistors is applied. Light
control is decided by the OSC. frequency of CT2
and the applied voltage to Adj2 terminal.
Fig.5 shows how the applied voltage to Adj2
terminal relates itself to light control.
The voltage range of Adj2 terminal available for
light control is 0.1V to 2.4V.
When the voltage is 2.4V or more, light control
duty becomes minimum(10%), and when it is
0.1V or less, light control duty becomes 100%.
Minimum duty is available by connecting Adj2
terminal to Vref terminal.
Output waveform on above mentioned stage is
shown in Fig.6(a) to Fig.6(c). Fig6(a) shows
100% light controlled state, Fig.6(b) middle state
(50% light controlled), Fig6(c) minimum duty
state.
