fixed duty ratio of 75% are also available (product type C).
With the S-8351 Series, a step-up switching regulator can be
configured by using an external coil, capacitor, and diode. The
built-in MOS FET is turned off by a protection circuit when the
voltage at the CONT pin exceeds the limit to prevent it from
being damaged. This feature, along with the mini package and
low current consumption, makes the S-8351 Series ideal for
applications such as the power supply unit of portable
equipment.
