    CXSB6609系列由双通道同步整流降压DC-DC转换器和带延迟VD构成。DC-DC转换器是内置了0.35Ω(TYP.)P通道驱动晶体管,及0.35Ω(TYP.)N通道同步整流开关晶体管的降压用同步整流DC/DC转换器。通过降低内置晶体管的导通电阻，能提供高达800mA的高效率,稳定电流。开关频率高达1MHz,能选择小型电感。内置了UVLO欠压锁定(Under Voltage Lock Out)功能，输入电压在1.8V以下（CXSB6609A为2.7V以下）时，强制停止内部驱动晶体管。内置了电压检测器,可以由外置电容任意地设定延迟时间。此外,附带手动复位功能，可以在任意时机送出复位信号。The CXSB6609 series consists of 2 channel synchronous step-down DC/DC converters and a voltage detector with delay circuit
built-in. The DC/DC converter block incorporates a P-channel 0.35Ω (TYP.) driver transistor and a synchronous N-channel
0.35Ω (TYP.) switching transistor. By minimizing ON resistance of the built-in transistors, the CXSB6609 series can deliver
highly efficient and a stable output current up to 800mA. With high switching frequencies of 1MHz, a choice of small inductor
is possible. The series has a built-in UVLO (under-voltage lock-out) function, therefore, the internal P-channel driver
transistor is forced OFF when input voltage becomes 1.8V or lower (for CXSB6609A, 2.7V or lower). The voltage detector block
can be set delay time freely by connecting an external capacitor. With the manual reset function, the series can output a
reset signal at any time.
