Description

FULL DATA SHEET (PDF, 552kB) Download   E-Mail The MAX8594 evaluation kit (EV kit) is a fully assembled and tested circuit board that evaluates the MAX8594 5-output PMIC with DC-DC core supply for low-cost PDAs. The MAX8594 COR1 4MHz step-down DC-DC converter supplies a pin-selectable 1V or 1.3V output at 250mA. A MAIN LDO supplies 3.3V at 500mA. A secure-digital (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 enable. An LCD bias boost DC-DC converter features an on-board MOSFET and True Shutdown™ when off and has its own logiccontrolled enable. A µP reset output clears 20ms (typ) after the COR1 output achieves regulation to ensure an orderly start. Included on the MAX8594, and available on the EV kit, are low-battery and dead-battery monitors. The MAX8594 EV kit operates from a 3.1V to a 5.5V supply.
