Data Sheet
Precautions on use of products
When the capacity of the output smoothing electrolytic capacitor C1 is made large, output may not rise.
1000µF to 2200µF is recommended. Set the rise time within 10ms.
Set the Vod electrolytic capacitor C3 to 10µF.
Be sure to use the VG terminal voltage within the operating voltage range.
Set the external starting resistor (R1+R3) to 720KΩ. When reducing the resistance value, start-up may fail.
Take note of the loss of the resistor when it is reduced.
This product has built-in over current (reset type) protection function to prevent destruction at abrupt error.
These protection functions are effective for prevention against destruction owing to abrupt accident,
therefore, avoid using them for continuous protection circuit operating, or at transition
