This is the Mini 560 ( Mini560 ) small buck (step down, output voltage lower than input) DC-DC converter, you can provide input voltage between 7v and 20v and get output voltage of 5v at up to whopping 5A comfortably continuous in my tests.
Ripple on my DIY test equipment was observed to be pretty low for such devices at all loads and input voltages, I don’t think I saw anything larger than 300mVpp even at 5A and mostly under 100mV, quite impressive for a small chinese converter!
Over current appears to kick in at about 8A, and over-temperature in my tests started occurring from about 6.5A (in a cool office). Both over current and over temperature seem to require a power-cycle to reset, it doesn’t seem to self reset.
Please note that this module is probably not suitable for loads with large capacitances in excess of 220uF unless they have inrush limiting, as inrush current can trip the over current protection (certainly at 440uF unlimited inrush capacitance it trips on start). Most devices you are going to be running off 5v are unlikely to have such high capacitance anyway, but worth mentioning.
I have performed a range of characterisation tests on these devices please download this PDF for the full test results of the Mini 560 module so you can properly evaluate suitability for your task.
