一,产品概述(General Description)
The CXSD6133B is a current mode monolithic buck switching regulator.
Operating with an input range of 4.7V~18V, the CXSD6133B delivers 2A 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 ripples.Current mode control provides
tight load transient response and cycle-by-cycle current limit.The CXSD6133B
guarantees robustness with short-circuit protection, thermal protection,current
run-away protection, input under voltage lockout.The CXSD6133B is
available in 6-pin TSOT23-6 package, which provides a compact solution
with minimal external components.
