The 2A LM3435 driver ... RGB LEDs with one inductor. The device includes an I²C control interface for LED-current control. Other portable- or pocket-projector LED designs require a separate driver for ...

The new driver uses a high-gain constant-current circuit (460×) to pump a 150 mA LED with its 2-mA output current. The internal PWM (pulse width modulation) circuit can be set for 16 tones each RGB, ...
