MP3356 Datasheet, PDF (1/10 Pages) Monolithic Power Systems – High Voltage Photo Flash Charger and IGBT Driver for DSC

The Future of Analog IC Technology
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.
