MAX8901A - Highest Efficiency Supply

General Description

High Efficiency, Up to 91% 2.6V to 5.5V Input Voltage Range Fixed-Frequency Operation

Key Features

  • MAX8901A/MAX8901B The MAX8901A/MAX8901B step-up converters drive from two to six series-connected white LEDs (WLEDs) with constant current to provide uniform WLED intensity for LCD backlighting in cell phones, PDAs, and other handheld devices. The MAX8901_ operate at a fixed 750kHz (typ) switching frequency, allowing for tiny external components, and are optimized for the highest possible efficiency over the full 1-cell Li+/Li-Poly battery range. These converters use a single input (ON) to ena.
