产品概述 返回TOP
The CXPU33105 provide a complete power supply solution for digital video. They improve performance, component count, and size compared to other multi-channel controllers in 1-cell Li-Ion battery designs. On-chip MOSFETs provide up to 92~95% efficiency for critical power supplies. Channel 1/2/3/4 operate at one fixed frequency of 1MHz to optimize size, cost, and efficiency. Channel 5 operate as LDO.
