产品概述
MAX1910EUB+ is a 1.5x/2x high-efficiency white LED charge pump. This is power LED with a regulated output voltage or current (up to 120mA) from an unregulated input supply. It is complete DC-DC converter requiring only 4 small ceramic capacitors and no inductors. Input ripple is minimized by a unique regulation scheme that maintains a fixed 750kHz switching frequency over a wide load range. Also included are logic-level shutdown and soft-start to reduce input current surges at start-up. It has two automatically selected operating modes such as 1.5x and 2x. 1.5x mode improves efficiency at higher input voltages while 2x mode maintains regulation at lower input voltages. Typical applications include white LED backlighting, cellular phones, PDAs, digital still cameras, MP3 Players and backup-battery boost converters.
