ST778 - ADJUSTABLE OUTPUT DC-DC CONVERTER

Download the ST778 datasheet PDF. This datasheet also covers the ST777 variant, as both devices belong to the same adjustable output dc-dc converter family and are provided as variant models within a single manufacturer datasheet.

Description

The ST777/778/779 are dc-dc converters that step-up from low voltage inputs requiring only three external components, an inductor (typically 22µH) and two capacitors.
