Application for timer-latch by detecting tube current and feedback 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.

 Cscp1: Terminal for capacitance for timer-latch set (few second)

2.5

Timer-L (Cscp1) = Cscp1 × 1.3 × 10−6

 Cscp2: Terminal for capacitance for timer-latch set (few millisecond)

1.25

Timer-L (Cscp2) = Cscp2 × 1.3 × 10−6
