Description
- weight: 485 g
Overview:
The module uses high-quality chips, high efficiency (up to 95%), low heat generation, maximum 5A current, and TI's op-amp control output current, making the overall output very stable.
This module uses a low-ESR filter capacitor to reduce ripple voltage to 50mV!

I am using these as energy-saving voltage reducers. There are two kinds of noise at the output: HF ringing from digital switching, and voltage ripple. I get rid of the ringing noise using a 8mm diameter ferrite ring with 3 turns of wire both plus and neg output wires. I get rid of voltage ripple with 78XX or LM317 linear regulators. The modules are rated 50 mV ripple, but my noise is much less than that - too low to measure on my O'scope.
Basically I have a 26V 1Amp supply from a transformer, and from that I want to provide +Variable voltage, +12 Volts and +8 Volts at as much current as can supply, and for these supplies to be short-circuit protected. To do so I use 3 modules, 3 ferrite rings and 3 linear regulators. Success !!

The inductor core is not correctly sized: it becomes super as soon as current goes above 1.5A
Placing another inductor is recommended
Otherwise work OK
