广州XR5040C(DC/DC降压IC）

一、DESCRIPTION
The XR5040C is a current mode monolithic buck voltage converter. Operating with an input range of 4.5V-16V, the XR5040C delivers 3A 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 XR5040C guarantees robustness with short circuit protection, thermal protection, current run-away protection, and input under voltage lockout.
The XR5040C is available in a 6-pin SOT23-6 package, which provides a compact solution with minimal external components.
