This is the one I use HDMI to Component Converter with Scaler Function, EASYCEL Aluminum 1080P HDMI to YPbPr, HDMI to RGB 5RCA Scaler Converter, HDMI Input to Component YPbPr Output Converter https://www.amazon.com/dp/B083ZF5BBP/ref=cm_sw_r_apan_glt_fabc_FK0W0SV0WXEZ1NYNGFR9
Yeah, it's this guy. I could do without the scaler. Didn't realize there were multiple versions!
I have used that ViewHD splitter and its a great product with limitations. I purchased one for stripping the HDCP copy protection from the hdmi output of my Satellite STB but that is not necessary if you're then planning to convert the splitter's hdmi output to a component input. The main drawback is that it's not rated to work with a 4k HDMI input.
I have not found an elegant all-in-one solution but I can vouch for the following products...

Importantly, both of these splitters will downscale a 4k 60Hz 4:4:4 signal to 1080p on the 2nd hdmi output (for your Slinbox) whilst allowing you to still enjoy a 4k signal from the other output (for your TV). They also have a micro USB power input so you can use a phone charger as a power source. If your TV box has a USB port you may be able to plug the cable into that for power.

HDMI to component scalers can be hit and miss. You are converting a digital signal to an analogue signal. Avoid "passive" converters (these are usually unpowered - replying only on the power provided by the HDMI input) as I've found them to be unreliable.
Read up on EDID management and read the instructions that come with the HDMI splitter that you purchase. You'll need to set the dip switches on the above HDMI splitters to get the HDMI signals right. If you purchase a splitter with no EDID management you may have problems splitting a 4k signal to a mixed 4k / 1080p output.
As with everything, you generally get what you pay for. Cheaper options are available but you should expect mixed results.
I found this a few weeks ago, but don’t personally own it:

Just wanted to share some images of the results you can expect with the Easycell branded HDMI to component “converter”. As someone pointed out a few weeks ago, it’s not merely a converter, but rather a transcoder, and while it’s not advertised on its description, it supports 480i, which means you can use it to hook up your Switch or any other modern console to an SDTV. The results are surprisingly nice for a $32 device! As is common with CRTs, the pictures above are not as vibrant as you will see in-person. It’s not a perfect device, though. There’s some sync issue that results in torn frames every 10-15 seconds, and it seems to handle 720p input better than other resolutions. I do perceive some lag, perhaps 1 frame or so, but everything is eminently playable. Still, I definitely recommend this if anyone was thinking of hooking up their Switch or PS5 (LOL) to an SDTV.
I had put a link in my thread comment. Here it is again.. Or you can search for Easycel HDMI to Component converter. It advertises that it can also output 480p, 576p, 720p, and 1080p/i. I assume it also transcodes when appropriate, but have not tested that functionality.
BTW , you can shorten your amazon links by chopping them off after their product id. Like below.
