产品详细介绍
产品概述
返回TOP
The CXSD62623 is a current mode monolithic buck switching regulator. Operating with an input range of 4.5V~60V, the CXSD62623 delivers 2A of continuous output current with an integrated high side N-Channel MOSFET. At light loads, the regulator operates in low frequency to maintain high efficiency and low output ripple. Current mode control provides tight load transient response and cycle-by-cycle current limit. The CXSD62623 guarantees robustness with short-circuit protection, thermal protection, current run-away protection, and input under voltage lockout. The CXSD62623 is available in 8-pin ESOP and 10-pin EMSOP package, which provides a compact solution with minimal external components.
