DESCRIPTION
The MP3336A is a compact, dual-channel, high-
power, flash LED driver that can drive up to 2A in
flash mode for each LED. The MP3336A
improves image and video quality in low light
environments for camera phones. The MP3336A
operates with a selectable 1/2/3/4MHz switching
frequency and uses a synchronous, current-mode
PWM boost converter to regulate the LED current
with two high current sources. The MP3336A
provides a highly efficient, optimized solution for
smaller PCB spaces.
The MP3336A features a standard I2C interface,
dual LED channels, rich protection modes, and
high power density and performance. The
MP3336A can also support flash, assist,
indicator, and 5V DC modes.
The cathodes of the dual-flash LED are
referenced to GND, which improves thermal
performance in layout. The MP3336A is available
in a WLCSP-20 (1.6mmx2.0mm) package.
