Operating Supply Voltage
2.7 V to 5.5 V
Maximum Power Dissipation
695.7 mW
Maximum Supply Current
35 uA
The MAX8571 evaluation kit (EV kit) contains a fully
assembled and tested circuit for evaluating the
MAX8571 step-up converter. This circuit operates with
2.7V to 5.5V input supply and provides a regulated 18V
output at up to 10mA. The output voltage is adjustable
from V
The MAX8571 EV kit contains a second unpopulated
circuit to accomodate a larger inductor and diode for
the higher-current-limited MAX8574 and MAX8575.
Either circuit can be used to evaluate any of the parts in
the MAX8570 family.
