dd212 最大400ma二倍升壓驅動單顆led恒流芯片  

         dd212 is designed specifically for driving a white led as a light source with low supply voltage.  like a charge pump,  dd212 doubles the supply voltage,  but only requires one external component, a capacitor. the built-in oscillator generates a 50% duty-cycle and 350khz-frequency clock. dd211 also consumes little power with cmos integrated circuits. dd212 comes in a small die that makes packaging it  within a led module be easy.  dd212””s  small  package,  sot25 occupies only little area for portable device, such as a handset. dd212 also has an en pin to enable the chip, shutdown the dd212, the operation current is lower than 0.1ua.

       features:  low supply voltage, 1.5v~5.5v; only one external component, a capacitor needed; high power output 400ma@vdd=3v;  low shutdown supply current;  it is easy to package dd212 within a led module .

applications: white led indicators”” drivers ; white led back lighters for low-voltage wireless handsets
