DESCRIPTION

The MP3360 is a fast, highly efficient and

precision high voltage photo-flash charger for

camera phone xenon flash.

The MP3360 has programmable peak currents

of

1.5A/1.4A/1.3A/1.2A/1.1A/1.0A/0.9A/0.8A

/0.75A/0.7A/0.65A/0.6A/0.55A/0.5A/0.45A/0.4A.

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 +/-2.5% output

voltage charge accuracy. MP3360 also has an

integrated IGBT driver with a regulated 2.7V

gate voltage.

MP3360 is available in the 10-pin, 2X2 flip chip

package.
