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.
