XCL205,XCL206,XCL207Series Inductor Built-in Step-Down “micro DC,DC” Converters
●GENERAL DESCRIPTION:
■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:1.8V～6.0V). 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 0.42ΩP-channel driver transistor and 0.52Ω N-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 becomes 1.4V or lower.
■XCL205B(G,F)/XCL206B(G,F)/XCL207B(G,F) series provide short-time turn-on by the soft start function internally set in 0.25 ms (TYP). XCL205B(C,G,F) /XCL206 B(C,G,F) / XCL207B(C,G,F) integrate C-L auto discharge function which enables the electric charge stored at the output capacitor C-L to be discharged via the internal auto-discharge switch located between the L-X and V-SS pins. When the devices enter stand-by mode, output voltage quickly returns to the V-SS level as a result of this function.
