- Part of the XCL205 comparator family.
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=1.04mm). A stable power supply with an output current of 600m A is configured using only two capacitors connected externally. Operating voltage range is from 2.0V to 6.0V(XCL20x G: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 0.42Ω P-channel driver transistor and 0.52Ω Nchannel 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 the0automatic 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 bees 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 0.25ms. XCL205B(C,G,F) /XCL206 B(C,G,F) / XCL207B(C,G,F) 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.
