Description
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 50µA. 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 2.2µF input and output capacitors while maintaining low ripple voltage. The MAX8884Y/MAX8884Z have individual enables for each output, maximizing flexibility.

The MAX8884Y/MAX8884Z are available in a 16-bump, 2mm x 2mm CSP package (0.7mm max height).

An evaluation kit is available:  MAX8884EVKIT
