9 Power Supply Recommendations

The UCC28600 is intended for AC-to-DC adaptors with input voltage range of 85 VAC(rms) to 265 VAC(rms)  using the flyback topology.  This controller can be used in supplies from a few Watts of power up to 200 Watts limited only by the practical use of a DCM flyback in regards to peak currents and output capacitor component size.  The UCC28600 can be used in bias supplies for LCD monitors, TVs, and set-top boxes, as well as AC-to-DC adapters for energy-efficient supplies.
