Description
General part information
MAX8668 Series
The MAX8667/MAX8668 dual step-down converters with dual low-dropout (LDO) linear regulators are intended to power low-voltage microprocessors or DSPs in portable devices. They feature high efficiency with small external component size. The step-down converters are adjustable from 0.6V to 3.3V (MAX8668) or factory preset (MAX8667) with guaranteed output current of 600mA for OUT1 and 1200mA for OUT2. The 1.5MHz hysteretic-PWM control scheme allows for tiny external components and reduces no-load operating current to 100µA with all outputs enabled. Dual low-quiescent-current, low-noise LDOs operate down to 1.7V supply voltage. The MAX8667/MAX8668 have individual enables for each output, maximizing flexibility.The MAX8667/MAX8668 are available in the space-saving, 3mm x 3mm, 16-pin thin QFN package.ApplicationsCell Phones/SmartphonesDigital Cameras, CamcordersHandheld InstrumentsPCMCIA CardsPDA and Palmtop ComputersPortable MP3 and DVD Players
