Applications/Uses

Description

The MAX8805W evaluation kit (EV kit) is a fully assembled and tested printed-circuit board (PCB) that demonstrates the highly integrated MAX8805W stepdown DC-DC converter optimized for dynamically powering the power amplifier (PA) in WCDMA or NCDMA handsets. The MAX8805W EV kit can dynamically control the step-down output voltage in the 0.32V to VBATT range from a 2.7V to 5.5V input-voltage range, and delivers 650mA of load current in low-power mode. In high-power mode, the step-down output is directly connected to the input by the internal 60mΩ bypass pFET. Two low-noise LDOs are also integrated in the MAX8805W. The MAX8805W EV kit can also evaluate the MAX8805X/MAX8805Y/MAX8805Z. To evaluate the MAX8805X/MAX8805Y/MAX8805Z, order a free sample along with this EV kit.
