MAX8594 Description
The MAX8594/MAX8594A plete 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 ponents. Featured are three linear regulators, a boost DCDC converter for LCD bias, an efficient 4MHz buck DC-DC...
