目录
The CXSD6138 is a current mode monolithic buck voltage converter. Operating with an input range of 4.5V-18V, the CXSD6138 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 CXSD6138 guarantees robustness with over current protection, thermal protection, start-up current run-away protection, and input under voltage lockout. The CXSD6138 is available in a 6-pin TSOT23-6 package, which provides a compact solution with minimal external components.
