产品概述 返回TOP
The CXSD62571 is a current mode monolithic buck voltage converter. Operating with an input range of 3.8V-18V, the CXSD62571 delivers 2.7A of continuous output current with two integrated N-Channel MOSFETs. At light loads, regulators operate in low frequency to maintain high efficiency and low output ripple. The CXSD62571 guarantees robustness with short circuit protection, thermal protection, current run-away protection, and input under voltage lockout. The CXSD62571 is available in a 6-pin SOT563 and TSOT23-6 package, which provides a compact solution with minimal external components.
