How much current? What are you powering?12v automotive application.
Application: LED clock
Update: Need a solution with lead-wires. Heat-sink? Noise would be a problem for the automotive project.
Just search ebay for a LM2596 adjustable module and set it for 9V or 10V. It should cost no more than US$1 incl postage.

... and give up ever using the AM radio in the car again...
The point is that those Chinese switchers are HORRIBLE RFI generators...Has anyone used AM radio this century?.
Let me guess, put the LM25XX pcb in a shielded enclosure, with ferrite common-mode filters on both the input wires and output wires including filter capacitors? That is about the minimum that it takes to quiet those things down... Been there, had to do that....its all down to the job being done right.
Yes. Otherwise it would be around and advertisers wouldn't waste their money.Has anyone used AM radio this century?.
Mike at first I thought the enclosure was just plastic, after seeing inside a injector control module yes its metalized for screening, and there was what looked like some Emi filtering stuff, vehicle manufacturers probably have to conform to a load of rules.
I have a dual lighter socket to usb converter and if I charge my phone with it I can't listen to am radio in weak signal areas.
I have the same with FM radio. In my 5 series, my USB adaptor obliterates all but the strongest stations. The only one that does not cause a problem is the dual USB metal canned adaptor. That works perfectly - keeps the noise internal
