MAX8858ETJ+ Products
The MAX8858ETJ+ PMIC provides a complete power-supply solution for digital still cameras (DSCs) and digital video cameras (DVCs). The MAX8858ETJ+ improves performance, component count, and board space utilization compared to currently available solutions for two AA cell and dual-battery 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 MAX8858ETJ+ is bootstrapped from VVSU.
  • MAIN synchronous-rectified step-up DC-DC converter (M) with active discharge for DSP I/O supply voltage.
  • SDZ synchronous-rectified step-down DC-DC converter (SDZ) with active discharge for DSP DDR supply voltage.
  • Low-voltage (down to 1V) synchronous-rectified step-down DC-DC converter (SD) with active discharge for DSP core supply voltage.
  • High-voltage step-up DC-DC converter (CCDBST) for CCD imagers or positive LCD bias supplies.
  • Transformerless inverting DC-DC converter (CCDINV) with active discharge for CCD imagers or negative LCD bias supplies. This converter can connect directly to two AA batteries.
Individual ON_ inputs provide independent on/off control for the SU, CCDBST, and CCDINV converters, while dual-function inputs allow independent on/off control or power-up sequencing of the MAIN, SDZ, and SD converters. The MAX8858ETJ+ is available in a 5mm x 5mm x 0.8mm, 32-pin thin QFN package and operates over the -40°C to +85°C extended temperature range.
