    | Partname: | ST778ACD |  | Description: | LOW VOLTAGE 3-3.3V/5V/ADJUSTABLE OUTPUT DC-DC CONVERTER WITH SYNCHRONOUS RECTIFIERS |  | Manufacturer: | SGS-Thomson Microelectronics |  | Datasheet: | PDF (344K). Click here to download *)
 |  | The ST777/778/779 are dc-dc converters that step-up from low voltage inputs requiring only three external components, an inductor (typically 22H) and two capacitors. The device include a Sinchronous Rectifier that eliminates the need for an external catch diode, and allows regulation even when the input is greater than the output.
