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.

Key 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.
