产品说明
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
