So from that, I am assuming I should remove both the 100K and 56K from the DC converter board to leave the EN to float freely.

Other manufacturers omit these components and / or slightly re-design the board to save money but you can't tell unless you look closely.

Im using mine to step down 12v to 5v, and yes the tiny trim pot is a little fiddly to adjust but be patient and steady your hand, it is possible. By using the Co-Browse feature, you are agreeing to allow a support representative from DigiKey to view your browser remotely.The thing to remember about buck regulators is; if the series switch transistor fails SC - it dumps the full unregulated voltage into the load. I'm not sure how much they'll be able to help since the Buck converters are a third party device but it's at least worth asking.

Without some testing any design no matter how simple could end up blowing out something much more expensive.There is much confusion regarding how to make meaningful design decisions when converting a datasheet’s thermal resistance parameters. The MP1584 is a high frequency step-down switching regulator with an integrated internal high-side high voltage power MOSFET. Now I'm pleased to report my entire project draws a tad under 40uA at standby - which is very close to the predicted estimates for the design. The alternative is; protect the load with a crowbar SCR - if you're charging a battery; isolate it with an anti discharge diode so crowbar activation doesn't endanger the battery. This circuit node is where one or more power semiconductor switches (such as a MOSFET or diode) connect to a magnetic energy-storing device (such as an inductor or transformer winding).
