The MAX8884Y/MAX8884Z step-down converters with dual low-dropout (LDO) linear regulators are intended to power low-voltage microprocessors, DSPs, camera and Wi-Fi modules, or other point of load applications in portable devices. These ICs feature high efficiency with small external component size. The step-down converter output voltage is pin selectable between 1.2V and 1.8V, and provides guaranteed output current of 700mA. The 2/4MHz hysteretic-PWM control scheme allows for tiny external components and reduces no-load operating current to 50A. Two low quiescent current, low-noise LDOs operate down to 2.7V supply voltage. Two switching frequency options are available--MAX8884Y (2MHz) and MAX8884Z (4MHz)--allowing optimization for smallest solution size or highest efficiency. Fast switching allows the use of small ceramic 2.2F input and output capacitors while maintaining low ripple voltage. The MAX8884Y/MAX8884Z have individual enables for each output, maximizing flexibility.
