DESCRIPTION

The MP3356 is a fast, highly efficient and

precision high voltage photo-flash charger for

DSC xenon flash.

The MP3356 has a peak current of 1.5A. A

50V, 0.5Ω internal power switch lowers

transformer turns ratio and switching losses

associated with the primary leakage inductance

and winding capacitance. Integrated secondary

feedback resistors provide +/-2.5% output

voltage charge accuracy. MP3356 also has an

integrated IGBT driver.

MP3356 is available in the 10-pin, 2X2 flip chip

package.
