MP3336A

Dual-Channel, Flash LED Driver

with 2A/Ch and I²C Interface

DESCRIPTION

FEATURES



2.7V~5.5V Input Voltage

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.

1/2/3/4MHz Selectable Max F_sw

_swFold-Back Function

400kHz I²C Compatible Interface

Standby/Flash/Assist/Indicator/5V DC

Modes

Flash Mode

Up to 2A/Ch Programmable Current with

±7% Accuracy for Each LED, 7.84mA/Step

Assist Mode

Up to 319mA/Ch Programmable Current



with ±7% Accuracy for Each LED,

1.25mA/Step

Indicator Mode

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.



Works in 31.5kHz PWM Dimming Mode with

2/16, 3/16, 4/16, 5/16 Duty Cycles

Used for Blinking and 128/256/512ms

Selectable Blinking Time



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.
