MAXIM INTEGRATED / ANALOG DEVICES MAX1910EUB High-Efficiency White LED Charge Pump

The MAX1910EUB+ from Maxim Integrated Products is a high-efficiency white LED charge pump available in a 10-pin µMAX package. It operates as a 1.5x or 2x switching regulator, providing a regulated output voltage or current up to 120mA from an unregulated input supply ranging from 2.7V to 5.3V. This compact DC-DC converter requires only four small ceramic capacitors and no inductors, simplifying design and reducing board space. The device features a fixed 750kHz switching frequency with a unique regulation scheme that minimizes input ripple over a wide load range. Additionally, it includes logic-level shutdown and soft-start functions to reduce inrush current during startup. It automatically selects between two operating modes: 1.5x mode, which improves efficiency at higher input voltages, and 2x mode, which maintains regulation at lower voltages. Suitable applications include white LED backlighting, cellular phones, PDAs, digital still cameras, MP3 players, and boost converters for backup batteries.
