目录产品概述 返回TOP The CXPU33109 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 AA, 1-cell Li-Ion, and multi-battery designs. On-chip MOSFETs provide up to 92~95% efficiency for critical power supplies. All channels DC/DC operate at one fixed frequency of 1.5MHz/750KHz to optimize size, cost, and efficiency. All Synchronous converters operate at pulse skipping mode at light load. They also feature True-Shutdown as well as internal compensation to minimize external component count..产品特点 返回TOP „ 1.5V ~ 5.5V Input Voltage Operation. „ 95% Efficient DC/DC Converter „ Highly Integrated 7-CH DC/DC with integrated Power MOSFETs „ Main Channel Selectable Buck or Boost for 2*AA or Li-Ion Application „ Built-in 6 Channel Synchronous Rectified Current-Mode PWM/PSM Converter, 1 Channel Non-Synchronous Rectified Current-Mode PWM Converter. „ Boost Type with LED open protection LED Driver „ 32-steps brightness control by I2 C for LED Driver „ Built-in HV LDO and RTC LDO „ Built-in 4 LDO regulators „ Low Power Consumption ( Sleep Mode ) < 10μA. „ Built-In Selectable Power ON/OFF Sequence for 4 Channel Synchronous Rectified Converter. „ Built-In Power ON/OFF Sequence by I2C for CCD+,CCD- power, and HVLDO. „ Built-In Short Circuit Protection (SCP) & Under Voltage Protection (UVP) „ Cycle-by-Cycle current limit for DC/DC Converter „ Built-In Thermal Shutdown Function. „ Built-In Battery OVP Function. „ Built-In Soft-Start Function. „ Built-In True Shutdown in Boost Converter. „ Fixed 1.5MHz/750KHz Operating Frequency. „ TQFN40 Package (5mmx5mm). 应用范围 返回TOP DSC and DV Power Supply 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！
