产品概述
CXSD62649 is a current mode monolithic buck switchingregulator. Operating with an input range of 4.5V~40V, the CXSD62649 delivers 1.5A of continuous output current with two integrated N-Channel MOSFETs. The internal synchronous power switches provide high efficiency without the use of an external Schottky diode. 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 CXSD62649 guarantees robustness with short-circuitprotection, thermal protection, current run-away protection,and input under voltage lockout.The CXSD62649 is available in 6-pin SOT23-6L package,which provides a compact solution with minimal external components.
