General Description

The MAX1561/MAX1599 step-up converters drive up to six white LEDs with a constant current to provide backlight in cell phones, PDAs, and other hand-held devices.

The step-up converter topology allows series connection of the white LEDs so the LED currents are identical for uniform brightness.

This configuration eliminates the need for ballast resistors and expensive factory calibration.
