Hi
I need to have 5V voltage source. I'm looking into buying either AZ 34063 (https://www.tme.eu/hr/en/details/az...egulators-dc-dc-circuits/diodes-incorporated/) or AP6503 (https://www.tme.eu/hr/en/details/ap6503sp-13/voltage-regulators-dc-dc-circuits/diodes-incorporated/).
AZ34063 recommends to have additional LC filter on the output, AP6503 doesn't.
I'm planning to have this used as 12V to 5V converter from my solar powered lead acid battery. I'll be powering Raspberry pi, RTL SDR receiver and RFM98 LoRa module. SDR is listening to 1420 MHz, and LoRa is transmitting at 433 MHz. My question is - do I need to do some special low pass filtering after buck converter output? I don't know if their switching produces noise up to, and over 433 MHz.
I'm assuming it's wise to have the buck converter shielded into metal enclosure and grounded, but that won't do anything if the noise is present on the output wire.
I even considered using buck to lower the voltage to around 7V and then using linear voltage regulator to bring it down to 5V. All options are still open.
Any advice is welcome.
