产品概述 返回TOP9Hm嘉泰姆
The CXSD62574 is a monolithic buck switching regulator based on I2 architecture for fast transient response. Operating with an input range of 4V~20V, CXSD62574 delivers 6A of continuous output current with two integrated N-Channel MOSFETs. The internal synchronous power switches provide high efficiency without the use of an external Schottky diode. At light loads, the regulator operates in low frequency to maintain high efficiency and low output ripples. CXSD62574 guarantees robustness with output short protection, thermal protection, current run-away protection, and input under voltage lockout. CXSD62574 is available in QFN3×3-20 package, which provide a compact solution with minimal external components.
