com 5-Output PMICs with DC-DC Core Supply for Low-Cost PDAs General Description The MAX8594/MAX8594A complete power-management chips for low-cost personal digital assistants (PDAs) operates from a 1-cell lithium-ion (Li+) or 3-cell NiMH battery.
They include all regulators, outputs, and voltage monitors necessary for small portable devices while requiring a bare minimum of external components.
Featured are three linear regulators, a boost DCDC converter for LCD bias, an efficient 4MHz buck DC-DC converter for core power, a microprocessor (µP) reset output, and low-battery shutdown in a 0.
8mm high thin QFN package.
The COR1 buck DC-DC converter supplies a pin-selectable output at 400mA.
All linear regulators feature PMOS pass elements for efficient low-dropout operation.
A MAIN LDO supplies 3.
3V at 500mA.
A securedigital (SD) card slot output supplies 3.
3V at 500mA, and a COR2 LDO supplies 1.
8V at 50mA.
Each output has its own logic-controlled enab...
