产品说明
DD211 is designed specifically for driving a high forward-voltage LED as a light source with low supply voltage. Like a charge pump, DD211 doubles the supply voltage, but only requires one external component, a capacitor. The built-in oscillator generates a 75% duty-cycle and 350kHz-frequency clock. DD211 also consumes little power with CMOS integrated circuits. DD211 comes in a small die that makes packaging it within a LED module be easy. DD211’s small package, SOT25 occupies only little area for portable device, such as a handset. Features : Low supply voltage, 2.0V~3.3V Only one external component, a capacitor needed Built-in resistor to limit the output current Low quiescent supply current It is easy to package DD211 within a LED module Applications: High forward-voltage LED Indicators’drivers High forward-voltage LED Back lighters for low-voltage wireless handsets
