NOTES ON USE

1. For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be exceeded.

2. The characteristics of this IC are highly dependent on peripheral circuits.

When selecting external components, refer to the specifications of each component and select so as not to exceed the ratings.

Some peripheral component selections may cause unstable operation.

Before use, sufficiently test operation using the actual equipment.

the set output voltage may not be output.

4. If the step-up ratio is high and excessive load current flows, the input current may be limited by the maximum duty limit and maximum current

limit protection and short-circuit protection may not activate.

6. For external components, use the components specified in the standard circuit examples and component selection methods.
