Note 1. Timer-latch time refers to the time under Cscp=1uF, Cscp2=0.1uF.
2. Amp. output is "H" when tube current I0 equals to 0, "L" when it is at
its minimum. Detection voltage is 2.5V("H" side), 0.25V("L" side).

Application for timer-latch by detecting tube current
and feecback voltage is available by using Iscp,
Cscp1, Cscp2 terminal.
Two kinds of setting for timer-latch time is available
by the setting of Cscp1, Cscp2. Each timer-latch
time is set by the formula below.

Triggers for protection operation
Detection of tube current
Detection of tube current is made by Iscp terminal.
Detection voltage for Iscp terminal is set 1.25V.
After power is on, when Iscp voltage does not rise
up to 1.25V by timer-L(Cscp1) time, or when Iscp
voltage becomes 1.25V or less after start-up,
abnormality is detected to move on to the protection
operation mode in Fig.1.
If Iscp voltage is less than 1.25V, light control is
not made(100%).
Detection of feedback voltage
Detection of feedback voltage is made by FB
terminal.
When FB terminal voltage goes down to FB low
detection voltage (0.25V) or less, or when it rise up
to FB terminal high detection voltage or more,
abnormality is detected to move on to the protection
operation mode in Fig.1.
