MAX8506 Evaluation Kit
General Description
The MAX8506 evaluation kit (EV kit) is a fully assembled
and tested surface-mount circuit board that demon-
strates the MAX8506 1MHz pulse-width-modulated
(PWM) step-down DC-DC converter optimized for pow-
ering the power amplifier (PA) in wireless applications.
The EV kit can dynamically control the output voltage in
the 0.4V to VIN range from a 2.6V to 5.5V input. It can
deliver 600mA of load current. The MAX8506 EV kit can
also be used to evaluate the MAX8507, which has a dif-
ferent gain, and the MAX8508, whose output can be
externally programmed for fixed 0.75V to 3.4V.
