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
