The CXSD62619 is a current mode monolithic buck voltage converter. Operating with an input range of 4.5V-28V, the CXSD62619 delivers 2A of continuous output current with two integrated N-Channel MOSFETs. At light loads, regulators operate in low frequency to maintain high efficiency. The CXSD62619 guarantees robustness with short circuit protection, thermal protection, current run-away protection, and input under voltage lockout. The CXSD62619 is available in a 6-pin SOT23-6 package, which provides a compact solution with minimal external components.
