一、DESCRIPTION
The XR5027 is a current mode monolithic buck voltage converter. Operating with an input range
of 3.8V-24V, the XR5027 delivers 2A 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 XR5027 guarantees robustness with short circuit protection, thermal protection, current run-away protection, and input under voltage lockout.
The XR5027 is available in a 6-pin SOT23 package, which provides a compact solution with minimal external components.
