XCL205/XCL206/XCL207 Series ETR2801-008 Inductor Built-in Step-Down “micro DC/DC” Converters ☆GreenOperation Compatible ■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. 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 0.52ΩN-channel switching transistor. As for operation mode, the XCL205 series is PWM control, the XCL206 series is automati
