dd211 二倍升壓100ma固定式恒流驅動芯片

      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
