DESCRIPTION

The MP3361 is a fast, highly efficient and

precision high voltage Xenon photo-flash

charger for Digital Still Cameras (DSC).

The MP3361 features a 1A peak current and

charges to 300V in 4 seconds from 4.2V battery

voltage. A 60V, 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 +/-3%

output voltage charge accuracy.
