Features

The uP6008 is a compact high-efficiency step-up converter

with integrated switch specifically designed to drive up to

seven white LEDs in series. Series connection of the LEDs

provides identical current resulting in uniform brightness.

Fixed 1.0 MHz operation allows smallest output ripple and

external component size. With high conversion efficiency

and small package, the uP6008 is suitable for portable

devices which PCB area is especially concerned.

The uP6008 features over-voltage protection against open-

LED situation. A single pin provides shutdown and accurate

LED dimming control. Other features includes internal soft

start, internal compensation, over-current protection, and

over temperature protection.

The uP6008 is available in SOT23 - 6L package.
