The MAX8858 PMIC provides a 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 two AA cell and dualbattery designs. On-chip power MOSFETs provide up to 95% efficiency for critical power supplies. The CCD inverter can operate directly from two AA/NiMH batteries without the use of any additional external components. Step-up synchronous-rectified DC-DC converter (SU). The MAX8858 is bootstrapped from VVSU.
