High-frequency oscillation frequency! A coil of size 0.8×0.45mm can be used.
The "XC9290/XC9291 Series" is a 600mA synchronous rectification DC/DC converter that employs HiSAT-COT control. By increasing the oscillation frequency, it aims to reduce the mounting area while achieving efficiency equal to or greater than conventional products through improvements in on-resistance and current consumption. This makes it suitable for devices that require a compact and low-profile design, as well as battery-operated devices such as mobile equipment. 【Features】 ■ HiSAT-COT control ■ Ultra-compact ■ 600mA ■ Step-down *For more details, please refer to the PDF document or feel free to contact us.
