The MAX8667/MAX8668 are dual step-down converters and dual low-dropout (LDO) linear regulators designed to power low-voltage microprocessors or DSPs in portable devices. They offer high efficiency and small external component size. The step-down converters can be adjusted from 0.6V to 3.3V (MAX8668) or factory preset (MAX8667), with a 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. The 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. They are available in a space-saving, 3mm x 3mm, 16-pin thin QFN package.
