Description

The MAX8621Z evaluation kit (EV kit) is a fully assembled and tested circuit board that evaluates the MAX8621Z dual step-down, DC-DC power-management IC for portable devices. The MAX8621Z EV kit BUCK1 and BUCK2 4MHz hysteretic step-down DC-DC converters are preset to 1.375V and 1.8V output voltages, respectively, and each can supply 500mA output current. The OUT1 and OUT2 LDOs each supply 2.6V (default EV kit setting) at 300mA. The OUT3 and OUT4 LDOs each supply 1.8V and 3V (default EV kit setting), respectively, at 150mA. Proper power sequencing is built in to the MAX8621Y/MAX8621Z. The four LDO output voltages are pin selectable by SEL1 and SEL2 for flexibility. OUT2, OUT3, and OUT4 have individual logic-controlled shutdown. A microprocessor reset output (RESET-bar) monitors VOUT1 and warns the system of impending power loss, allowing safe shutdown. RESET-bar asserts during power-up, power-down, shutdown, and fault conditions when VOUT1 is below its regulation voltage. An additional 200mA driver output is provided to control LED backlighting or provide an open-drain connection for resistors such as in feedback networks. The MAX8621Z EV kit operates from a 2.6V to 5.5V supply voltage. The MAX8621Z EV kit can also evaluate the MAX8621Y. To evaluate the MAX8621Y, order a free sample along with this EV kit.
