DD211
A DRIVER, CHARGE PUMP FOR HIGH FORWARD-VOLTAGE
LEDS WITH LOW SUPPLY VOLTAGE
General Description
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
