    产品概述;

    The XCL205/XCL206/XCL207 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control IC in one tiny package (2.5mm×2.0mm, H=1.0mm). A stable power supply with an output current of 600mA is configured using only two capacitors connected externally.

    Operating voltage range is from 2.0V to 6.0V(XCL20xG:1.8V6.0V). Output voltage is

    internally set in a range from 0.8V to 4.0V in increments of 0.05V. The device is operated by 3.0MHz, and includes 0.42Ω P-channel driver transistor and 0.52ΩN-channel switching

    transistor.

     As for operation mode, the XCL205 series is PWM control, the XCL206 series is automatic PWM/PFM switching control and the XCL207 series can be manually switched between the PWM control mode and the automatic PWM/PFM switching control mode, allowing fast response, low ripple and high efficiency over the full range of loads (from light load to heavy load). During stand-by, the device is shutdown to reduce current consumption to as low as 1.0μA or

    less.

    With the built-in UVLO (Under Voltage Lock Out) function, the internal driver transistor is forced OFF when input voltage ecomes 1.4V or lower. XCL205B(G)/XCL206B(G)/XCL207B(G) series provide short-time turn-on by the soft start function internally set in 0.25 ms (TYP). XCL205B(C,G) /XCL206 B(C,G) / XCL207B(C,G) integrate CL auto discharge function which enables the electric charge stored at the output capacitor CL to be discharged via the internal auto-discharge switch located between the LX and VSS pins. When the devices enter stand-by mode, output voltage quickly returns to the VSS level as a result of this function 产品特性;
