2. Externally Synchronized Operation
Case
When, with a power supply using the HA17384S/H or HA17385H, externally synchronized operation is
performed by applying an external syncronous signal to the R
T
/C
T
pin (pin 4).
Problem
Synchronized operation may not be possible if the amplitude of the external syncronous signal is too
large.
Reason
The R
T
/C
T
pin falls to a potential lower than the ground.
Remedy (counter measure)
In this case, clamping is necessary using a diode with as small a V
F
value as possible, such as a schottky
barrier diode, as shown in figure 18.
