PMP4472.2, DC Input, 3.3V/2A Cascaded Power Supply Reference Design
Progetto di riferimento di: Texas Instruments
PMP4472.2, DC Input, 3.3V/2A Cascaded Power Supply Reference Design. The PMP4472 is a power reference design with a high AC input, 5Vout, followed by a DC isolated output of 3.3V at 2A. It implements a high efficiency controller UCC28740 to provide 5V bus voltage and a step-Down Converter TPS54228. The design achieves good line and load regulation as well as good dynamic response and low output ripple voltage
