DC366A - LTC3200EMS8 Demo Board | Regulated Charge Pump White LED Driver, 2.7V ≤ VIN ≤ 4.5V, IOUT Drives 6 Parallel LEDs

Demonstration Circuit 366A is a low noise constant frequency regulated charge pump featuring the 100mA output current LTC3200. The demo board accepts a 2.7V to 4.5V input voltage and drives six white LEDs in parallel, resulting in 16.6mA per LED. Ballast resistors are employed to provide more uniform light intensity fromr the paralleled LEDs.
