MP3336A Dual-Channel, Flash LED Driver 2 with 2A/Ch and I C Interface DESCRIPTION FEATURES 2.7V~5.5V Input Voltage The MP3336A is a compact, dual-channel, high- 1/2/3/4MHz Selectable Max F sw power, flash LED driver that can drive up to 2A in F Fold-Back Function flash mode for each LED. The MP3336A sw 2 improves image and video quality in low light 400kHz I C Compatible Interface environments for camera phones. The MP3336A Standby/Flash/Assist/Indicator/5V DC operates with a selectable 1/2/3/4MHz switching Modes frequency and uses a synchronous, current-mode Flash Mode PWM boost converter to regulate the LED current Up to 2A/Ch Programmable Current with with two high current sources. The MP3336A 7% Accuracy for Each LED, 7.84mA/Step provides a highly efficient, optimized solution for Assist Mode smaller PCB spaces. Up to 319mA/Ch Programmable Current 2 with 7% Accuracy for Each LED, The MP3336A features a standard I C interface, 1.25mA/Step dual LED channels, rich protection modes, and Indicator Mode high power density and performance. The Works in 31.5kHz PWM Dimming Mode with MP3336A can also support flash, assist, 2/16, 3/16, 4/16, 5/16 Duty Cycles indicator, and 5V DC modes. Used for Blinking and 128/256/512ms The cathodes of the dual-flash LED are Selectable Blinking Time referenced to GND, which improves thermal 5V DC Mode performance in layout. The MP3336A is available Output Constant 5V DC Voltage in a WLCSP-20 (1.6mmx2.0mm) package.
