0-30V, 0-7A Adjustable Switching Power Supply [CC-CV plus LED]

Overview Reviews (1)
DC to DC buck converters is a famous topology in the electronic and a widely used circuit in electronic devices. A buck converter steps down the input voltage while it increases the output current. In this article/video, I have discussed a DC to...

Smooth presentation and useful link to components. Good test equipment, perhaps more complex or significant figures than required for new users. All one needs is an adjustable CC, CV digital PSU from Banggood for ~ $65 for a source and cheap clever methods for a transistor controlled load and heatsink.

Critical values of ESR, DCR values of reactive parts on schematic, which are always given in TI's Webbench., which is free and other OEM's alike.
These affect the Q and resonance of stored energy when load is stepped or pulsed and also the efficiency.

Good use of spring probe, but missed better method of AC coupled coax to 50 Ohms.

Also missed the critical test of surge current and step load tests from critical parts of compensation in the design.
