NCP3133A Integrated Synchronous Buck Converter 3A 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. NCP3133A is available in 3 mm x 3 mm QFN−16 pin package. Features • High Efficiency in both CCM and DCM • High Operation Frequency at 1.1 MHz • Support MLCC Output Capacitor • Small Footprint, 3 mm x 3 mm, 16−pin QFN Package • Up to 3 A Continuous Output Current • 2.
