XD9261系列

COT控制 1.5A降压同步整流DC/DC转换器

*符合AEC-Q100 (Grade2) 标准

The XD9261 series is a group of synchronous-rectification type DC/DC converters with a built-in P-channel MOS driver transistor and N-channel MOS switching transistor, designed to allow the use of ceramic capacitors.

Output voltage is internally set in a range from 0.8V to 3.6V (accuracy: ±2.0%) increments of 0.05V. The device provides a high efficiency, stable power supply with an output current of 1.5A to be configured using only a coil and two capacitors connected externally. Oscillation frequency is set to 1.2MHz or 3.0MHz can be selected for suiting to your particular application.As for operation mode HiSAT-COT control excellent in transient response, allowing fast response, low ripple and high efficiency over the full range of loads (from light load to heavy load).
