(Note 1) Although the output voltage is configurable at 0.8 V and higher, it may be limited by the SW min ON pulse width.

For the same reason, although the output voltage is configurable at 8.5 V and more, it may be limited by the SW minimum OFF pulse width.

For the configurable range, please refer to the Output Voltage Setting in Selection of Components Externally Connected (page 30).

(Note 2) This parameter is for 0.5 A output. Not tested.

(Note 3) Ceramic capacitor is recommended. The capacitor value including temperature change, DC bias change, and aging change must be considered. If a bulk

capacitor is used with Input ceramic capacitors, please select capacitors referring page 33.
