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.
