DD211 二倍升壓100mA固定式恒流驅(qū)動(dòng)芯片
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 all die that makes packaging it within a LED module be easy. DD211's all 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
