    The CXSD6145B is a wide input range, high efficiency,DC-to-DC step-down PGf嘉泰姆

switching regulator, capable of delivering up to 3A of output current. Current PGf嘉泰姆

mode PWM control allows the use of small external components, such as ceramicPGf嘉泰姆

 input and output caps, as well as small inductors, while still providing low outputPGf嘉泰姆

 ripples.On top of the integrated internal synchronous rectifier that eliminates PGf嘉泰姆

external Schottky diode, Overall PGf嘉泰姆

  CXSD6145B is a highly efficient and robust solution for DC-DC step-down PGf嘉泰姆

applications that requires wide input ranges.PGf嘉泰姆

  CXSD6145B is available ESOP8 Packages.PGf嘉泰姆
