la1631a-尊龙凯时入口

overview  the la1631a is an  easy to use  synchronous stepdown buck, which  integrated with highside and low-side  power mosfets. the  la1631a can provide  up to 1a of output current efficiently with  current-mode control for fast loop  response.  wide 4.5v to 48v input range  accommodates a variety of power meter  step-down applications. la1631a uses  high duty cycle and low dropout mode for  low power meter input voltage conditions.  the la1631a achieves high power  conversion efficiency over a wide load  range by scaling down the switching  frequency under light-load conditions to  reduce switching and gate driving losses.  the la1631a has built-in full protection  features, cycle-by-cycle current limit,  hiccup mode short-circuit protection, and  thermal shutdown in case of excessive  power dissipation. la1631a is available in  a cost-effective sot23-6 package.
