DESCRIPTION

The MP3351 is a fast, highly efficient, precision

high voltage photo-flash charger with integrated

IGBT driver for xenon flash applications. The

programmable peak current from 300mA to 2A.

A 200mΩ internal power switch minimizes the

conduction loss. 60V maximum output voltage

lowers the transformer turns ratio and improves

switching loss associated with the primary

leakage inductance. External feedback provides

3% charge accuracy.

The MP3351 is available in a 16-pin 3mm x

3mm QFN package
