3. Before concluding power module damage
Verify following items before concluding power module
damage.
1)No output voltage
● Is specified input voltage applied?
● Are the ON/OFF control terminal (CNT terminal),
output voltage trimming terminal(TRIM) correctly
connected?
● For cases where output voltage adjustment is used,
is the resistor or variable resistor setting, connec-
tions correctly done?
● Are there no abnormalities in the output load used?
2)Output voltage is high
● For cases where output voltage adjustment is used,
is the resistor or volume setting, connections cor-
rectly done?
3)Output voltage is low
● Is specified input voltage applied?
● For cases where output voltage adjustment is used,
is the resistor or variable resistor setting, connec-
tions correctly done?
● Are there no abnormalities in the output load used?
4)Load regulation and line regulation is large
● Is specified input voltage applied?
● Are the input terminals and the output terminals firmly
connected?
● Is the input or output wire too thin?
5)Output ripple voltage is large
● Is the measuring method used the same or equiva-
lent with the specified method in the Application
Notes?
● Is the input ripple voltage value within the specified
value?
