The XCL205/XCL206/XCL207 series is a synchronous step-down micro DC/DC converter that integrates an inductor and a control IC in a tiny package. It features high efficiency, stable power supply output, and fast response.
The XCL205, XCL206, and XCL207 are synchronous step‑down micro DC/DC converters that integrate an inductor and control IC in a 2.5 mm × 2.0 mm × 1.0 mm package. They provide 600 mA output current from a 2.0 V‑6.0 V input and support output voltages from 0.8 V to 4.0 V in 0.05 V steps. The series targets mobile phones, Bluetooth headsets, PDAs, digital cameras, and other portable electronics.
The document lists pin assignments, absolute maximum ratings, electrical characteristics, and typical performance curves. It also describes control modes (PWM, PWM/PFM automatic, PWM/PFM manual) and features such as soft‑start, auto‑discharge, UVLO, and standby shutdown. Detailed tables give values for efficiency, oscillation frequency, on‑resistance, and temperature limits.
