MP3332 Dual-Channel Flash LED Driver, 2 1.5A/Ch with I C Interface FEATURES DESCRIPTION 2.7V~5.5V Input Voltage The MP3332 is a dual-channel, flash LED driver Dual-Channel, 1.5A/Ch Flash Current with for high-resolution camera phones. It comes in a +/-7% Accuracy very compact package and is highly efficient at 1/2/3/4MHz Selectable Switching Frequency improving image and video quality in low-light and Switching Frequency Foldback environments. The synchronous boost converter Function operates at 1/2/3/4MHz to provide higher 2 400kHz I C Compatible Interface efficiency and an optimized solution for smaller Standby/Flash/Assist/Torch/Indicator/5V DC PCB spaces. Modes 2 The MP3332 features a standard I C interface, Flash Mode: dual LED channels, high-power density, and Up to 1.5A/Ch Programmable Current with multiple protection features. The MP3332 +/-7% Accuracy for Each LED supports flash, assist, torch, indicator, and 5V Assist/Torch Mode: DC modes. Up to 500mA/Ch Programmable Current with +/-7% Accuracy for Each LED To improve thermal performance, the cathodes of Indicator Mode: the dual flash LED are referenced to GND for a Works in 31.5kHz PWM Operation with 2/16, better layout. It is available in a WLCSP-16 3/16, 4/16, 5/16 Duty Cycle (1.7mmx1.7mm) package. 128ms/256ms/512ms Selectable Blinking Time 5V DC Mode: Constant 5V DC Output External Torch/Strobe LED Forward-Voltage Balance to Improve Efficiency 1A to 4.2A Programmable Input DC Current-Limit Protection Low-Battery Voltage Protection LED Short/Open Protection VOUT-GND Short Protection Over-Voltage Protection (OVP) Over-Temperature Protection (OTP) NTC Detection and Protection Input Under-Voltage Lockout (UVLO) Protection Available in a WLCSP-16 (1.7mmx1.7mm) Package APPLICATIONS LED Flash for Smart Phones Cameras for Tablet Digital Still Camera All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
