Application example
Electrical characteristic curves
1.5
Ambient temperature :
10C
～
60C
Operation notes
(1) The output current should be reduced according to an increase in the output voltage or ambient
temperature. Use the module within the derating curve range.
(2) The protection circuit for output current is not incorporated. Be sure to take safety measures such as
fusing if short-circuit loads or overcurrent is probable.
(3) External capacitor
Since the switching system is employed for the purpose of changing the voltage, ripple current flows to the
capacitor to be added to pins 1, 9. Select the product of which allowable ripple current is more than this
value.
