MAX8901B - Highest Efficiency Supply

Download the MAX8901B datasheet PDF. This datasheet also covers the MAX8901A variant, as both devices belong to the same highest efficiency supply family and are provided as variant models within a single manufacturer datasheet.

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.
