Operation notes

Electrical characteristic curves

Application example

(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, 4, 11, 13, 14, 17. Select the product of which allowable ripple current is

more than this value.
