MAX8858EVKIT：Evaluation Kit for the MAX8858
The MAX8858 evaluation kit (EV kit) is a fully assembled
and tested PCB for evaluating the MAX8858 power-management
IC (PMIC). The MAX8858 PMIC provides
a compact and complete power-supply solution for digital
still cameras (DSCs) and digital video cameras
(DVCs). The MAX8858 improves performance, component
count, and board space utilization compared to
currently available solutions for 2AA cell and dual-battery
designs. On-chip power MOSFETs provide up to
95% efficiency for critical power supplies. The CCD
inverter operates directly from two AA/NiMH batteries
without the use of any additional external components.
