700mA DC-DC Step-Down Converters  
with Dual 300mA LDO in 2mm x 2mm CSP  
Y/MAX84Z  
General Description  
Features  
o Step-Down Converter  
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 switch-  
ing frequency options are available—MAX8884Y (2MHz)  
and MAX8884Z (4MHz)—allowing optimization for small-  
est 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.
