(*1)

Use an appropriate ceramic capacitor according to the DC bias usage conditions (ambient temperature, input / output voltage)

so that the effective capacitance value is equal to or higher than the recommended component.

(*2)

If a tantalum or low ESR electrolytic capacitor is used for the CL, the ripple voltage will increase.

When using an electrolytic capacitor for the CL, connect a ceramic capacitor in parallel before use.

In addition, when a large-capacity ceramic capacitor, tantalum, low ESR electrolytic capacitor, etc. are used for the CL,

the following operations may occur.

(a) The output voltage may become unstable under heavy load.

(b) For products with an integral latch, the integral latch function may operate and the output voltage may not rise to the

target voltage if the current limit function continues after the start mode is completed.
