Technical Note
● Operation description
Enable control
The device can be controlled ON/OFF by EN terminal (13 pin) voltage.
An internal circuit starts when VEN reaches 1.4V.

Soft start time set function
As for BD8629FS, output can do soft start without overshoot by charging soft start capacity (CSS) connected between SS
and SGND terminal.
Also, soft start time (tss) can be set by setting soft start capacity (CSS) arbitrarily.
