The Future of Analog IC Technology
MP3360
Highly Integrated Photo Flash Charger
and IGBT Driver
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.
FEATURES
• Integrated 60V, 0.5Ω Power Switch
• Single wire digital interface for current limit
programming.
• 2.5% Charge Accuracy
• <1uA Shutdown Current
• Integrated IGBT Driver with Regulated Gate
Voltage
APPLICATIONS
• Mobile Phones with Xeon Flash
• Digital Still Cameras
• Optical Film Cameras
• PDAs with Xeon Flash
