The MAX8896 evaluation kit (EV kit) is a fully assembled and tested circuit for evaluating the MAX8896 dual stepdown converter with low-dropout (LDO) linear regulator. The MAX8896 EV kit operates from a 2.7V to 5.5V power supply or battery. The PA step-down output regulates to 2.5 times the voltage at REFIN (0.2V to 1.7V) and provides 700mA drive capability. RFOUT (step-down regulator followed by LDO) regulates to 2.8V and provides 200mA drive capability.
