MP3352

NOT RECOMMENDED FOR NEW DESIGNS

60V, 2.5A Integrated Photo Flash Charger with IGBT Driver and Quench

NRFND Datasheet

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.

Evaluation Tools

EV3336-C-00A Evaluation Kit Dual-Channel Flash LED Driver With 2A/Ch and I2C Interface Evaluation Board

The MP3336 is a dual-channel and high-power flash LED driver with very compact package. It can drive up to 2A in flash mode for each LED. It is usually applied for camera phones to improve image and video quality in low light environment. The device operates in1/2/3/4MHz synchronous, current-mode PWM boost converter to regulate the LED current with two high current source. The MP3336 provides an optimized solution for smaller PCB space and higher efficiency.

The MP3336 features standard I2C interface, dual LED channels, rich protection modes and high power density and performances. It supports flash/assist/torch/indicator/5V DC modes.

The cathodes of the dual flash LED are referenced to GND, which is better for layout to improve thermal performance. It is available in WLCSP20-1.6X2.0mm package.
