Product Details

Demonstration Circuit 395A is a Low Noise, Charge Pump White LED Driver featuring the LTC3202. The LTC3202 is a fractional charge pump LED driver that operates from 2.7V to 4.5V (3.3V nominal) and provides up to 125mA of LED current. The demo board includes 6 white LEDs in parallel, supplying approximately 20mA of current per LED.

Controls pins D0 and D1 set the values for the internal 2-bit DAC, which allows LED current to be adjusted for LED brightness control.
