MP3302

2.5V-6V輸入電壓，1.3A升壓WLED驅動器; ? 內部功率 MOSFET\n? 可驅動多達10個串聯(lián)白光LED\n? 效率高達87%\n? 單線調光控制\n? 1.3MHz 固定開關頻率\n? 負載開路關斷\n? 200mV 低反饋電壓\n? 欠壓鎖定（UVLO）保護、過溫關斷保護\n? 1.3A內部限流保護\n? 采用 TSOT23-5和2mm x 3mm QFN8封裝\n;

MP3302是一款升壓變換器，專用于為單節(jié)鋰離子電池驅動WLEDS陣列。MP3302 采用電流控制模式和定頻架構來調節(jié) LED 電流，可以通過外部電流采樣電阻來檢測 LED 電流。其 200mV 的低反饋電壓降低了功率損耗，提升了轉換效率。當由于開路出現(xiàn)過壓情況時，MP3302將被關斷。\n\n MP3302 具有輸入欠壓鎖定（UVLO）保護、限流保護和熱過載保護，當輸出過載時可防止芯片損壞。\n\n MP3302 采用小尺寸 5引腳TSOT23封裝或8 引腳2mmx3mm QFN 封裝。\n\n

MP3304A

2.5V-6Vin, 38V OVP, 1.3A, Boost WLED Driver; ●Internal Power MOSFET \n●Drives up to 10 Series White LEDs \n●Up to 88% Efficiency \n●PWM Dimming Frequency from 250Hz to 50kHz \n●2.2MHz Fixed Switching Frequency \n●Open Load Shutdown \n●Low 200mV Feedback Voltage \n●UVLO, Thermal Shutdown \n●Internal 1.3A Current Limit \n●Available in 2x3mm QFN8 Package\n;

The MP3304 is a monolithic step-up converter \ndesigned for driving arrays of WLEDs from 5V \ninput or a single cell Lithium Ion battery. The \nMP3304 uses current mode, fixed frequency \narchitecture to regulate the LED current, which is \nmeasured through an external current sense \nresistor. Its low 200mV feedback voltage reduces \npower loss and improves efficiency. \nThe MP3304 features up to 50kHz true PWM \ndimming, which allows the flexible control of the \nbacklighting luminance under wide range of the \nambient brightness, and also avoids the \npossibility of PWM dimming audible noise. \nThe MP3304 is turned off if an over-voltage \ncondition is present due to an open circuit \ncondition. MP3304 also includes under-voltage \nlockout, current limiting and thermal overload \nprotection preventing damage in the event of an \noutput overload. \nThe MP3304 is available in small 8-pin QFN \n2x3mm package.

The MP3304 features up to 50kHz true PWM dimming, which allows the flexible control of the backlighting luminance under wide range of the ambient brightness, and also avoids the possibility of PWM dimming audible noise. The MP3304 is turned off if an over-voltage condition is present due to an open circuit condition. MP3304 also includes under-voltage lockout, current limiting and thermal overload protection preventing damage in the event of an output overload.
