  • NCP3133A is a fully integrated synchronous buck converter for 3.3 V and 5 V step−down applications. It can provide up to 3 A load current. NCP3133A supports high efficiency, fast transient response and provides power good indicator. The control scheme includes two operation modes: FCCM and automatic CCM/DCM. In automatic CCM/DCM mode, the controller can smoothly switch between CCM and DCM, where converter runs at reduced switching frequency with much higher efficiency.
  • Features
