The MAX8569 evaluation kit (EV kit) is a fully assembled
and tested surface-mount circuit board demonstrating
the MAX8569A or MAX8569B 200mA step-up boost
converter. The EV kit comes with the MAX8569B
installed. The application circuits provide a 3.3V output
voltage capable of sourcing a maximum of 200mA load
current from a 1.5V to 5.5V input source. The MAX8569
features internal MOSFETs to reduce cost and size. It
also includes skip mode, which optimizes efficiency at
light loads to improve battery life. The MAX8569 EV kit
can also be used to evaluate the MAX8569A and
MAX8569B30 with minor PCB modification.
19-4556; Rev 0; 4/09
+ Denotes lead(Pb)-free and RoHS compliant.
Note: The MAX8569 EV kit is installed with the MAX8569B. To
evaluate the MAX8569A or MAX8569BETT30, order the corre-
sponding part along with the MAX8569 EV kit.
