一,产品概述(General Description)
The CXSD6142 is a current mode monolithic buck switching regulator. Operating with
an input range of 4.7V~40V, the CXSD6142 delivers 600mA 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 JTMB9341 guarantees robustness
with short-circuit protection,thermal protection, current run-away protection, and
input under voltage lockout. The CXSD6142 is available in 6-pin SOT23-6 package,
which provides a compact solution with minimal external components.
