DD211 二倍升压100mA固定式恒流驱动芯片

      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 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
