MAX158 Datasheet - Maxim

MAX158 High-Efficiency / 26V Step-Up Converter

The MAX1582 drives up to six white LEDs in series with a constant current to provide display backlighting for two (main and sub-) displays in cell phones and other hand-held devices. This configuration eliminates the need for ballast resistors and expensive factory calibration. The proprietary dual-.
