The Future of Analog IC Technology
MP3352
60V, 2.5A Integrated Photo Flash Charger
with IGBT Driver and Quench
DESCRIPTION
The MP3352 is a fast, highly efficient, precision
high-voltage photo-flash charger with integrated
IGBT driver for xenon flash applications. The
programmable peak current is up to 2.5A to
ensure fast charging time. A 200mΩ internal
power switch minimizes the conduction loss. In
addition, a 60V maximum voltage lowers the
transformer turns ratio and improves the
switching loss associated with the primary
leakage inductance. External feedback provides
3% charge accuracy.
The MP3352 is available in a 16-pin 3mm x
3mm QFN package.
