产品概述

返回TOP

The CXSD62617TC and CXSD62617TF are monolithic buck switching regulators based on I2 architecture for fast transient response. Operating with an input range of 4.5V~18V, CXSD62617TC and CXSD62617TF deliver 2A 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, CXSD62617TC operates in low frequency to maintain high efficiency. CXSD62617TC and CXSD62617TF guarantee robustness with output short protection, thermal protection, current run-away protection and input under voltage lockout. CXSD62617TC and CXSD62617TF are available in SOT23-6 package, which provide a compact solution with minimal external components.
