   产品概述 返回TOPqaa嘉泰姆

      The CXSU63040 is a synchronous rectifier,fixed switching frequency (1.2MHz typical), and current‐mode step‐up regulator. The device allows use of small inductors and output capacitors for USB devices. The current‐mode control scheme provides fast transient response and good output voltage accuracy. At light loads, the CXSU63040 will automatically enter in Pulse Frequency Modulation (PFM) operation to reduce the dominant switching losses. During PFM operation,the IC consumes very low quiescent current and maintains high efficiency over the complete load range.The CXSU63040 also includes current‐limit and overtemperature shutdown to prevent damage in the event of an output overload. The CXSU63040 is available in ESOP 8 packages
