700mA DC-DC Step-Down Converters with Dual 300mA LDO in 2mm x 2mm CSP
General 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 quiesce...
