Conclusion

Using the VIPer in the buck mode has its benefits for appliances and other industrial

equipment which require a reference to neutral. For currents up to 350 mA and voltages

greater than 10 V, it is beneficial to use this inexpensive power supply. The cost savings

compared to a transformer, opto-coupler, and low parts count, makes this solution very

attractive.
