产品详细介绍
产品概述
返回TOP
The CXSD62624 is a monolithic buck switching regulator based on COT architecture for fast transient response. Operating with an input range of 2.5V~6V, CXSD62624 delivers 2A of continuous output current with integrated P-Channel and 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. CXSD62624 guarantees robustness with output short protection, thermal protection, current run-away protection, and input under voltage lockout. CXSD62624 is available in DFN2X2-8 package, which provides a compact solution with minimal external components.
