产品概述 返回TOP
The CXPU33106A/CXPU33106B provide a complete power supply solution for digital cameras. They improve performance, component count, and size compared to other multi-channel controllers in 2-cell A(CXPU33106A/CXPU33106B), 1-cell LiIon(CXPU33106A/CXPU33106B), and multi-battery designs. On-chip MOSFETs provide up to 92~95% efficiency for critical power supplies. All channels DC/DC operate at Fixed 2MHz(CH1~CH4)/ 1MHz(CH5~CH7) Operating Frequency to optimize size, cost, and efficiency. The CXPU33106A/CXPU33106B is available in 32-pin TQFN (4X4) package.
