USB-PD source module/IC

[mtwieg]

For a device I'm developing, one of the requested features is that the device be capable of providing power to charge tablets/smartphones. In particular they want USB-PD, capable of 20W of power. Data transfer is not required (beyond supporting the power negotiation stuff). Device already has a 36V DC supply (could step this down to 12-24V if necessary).

I'm not familiar with modern USB specs at all, so I was hoping to find a breakout board/module solution. Not a product in a plastic housing, but a board I can solder onto another PCB assembly. It seems like there are lots of options for triggers on the sink side, but very little on the source side. Closest I can find is this thing, but the fact that Vin has to be wired into screw terminals is a pain.

Is there anything else I'm missing? I can't choose anything from Amazon/ebay/aliexpress/etc, needs to be sold through a "trustworthy" distributor (not sure if Mikroe meets that criteria). I'm surprised TI/STM/Cypress don't offer some options here.

This module is pretty good for their price. Supports almost all PD/QC modes up to 100W. Almost no voltage drop even at 100 Watt power consumption.

Without metal shell it will cost about 50 cents less, so I suggest to buy it with metal shell.

For 20W you can feed it with 12V 2-3 Amps.
Voltage doesn't matter, it supports up to 28V, but in order to get 20W you needs to provide at least 12V and enough current, the rest things will be done with module.

Optimal feed voltage to get max efficiency (minimum heating) at 100W output is 22-23 V. So you can feed it with 24V, it will be almost the same good.

Thanks... even if this thing is functional, I can't make use of it due to reasons I mentioned in my first post (can't use aliexpress as vendor, and would be very difficult to integrate this thing in the product).

If a chip vendor (TI/cypress/STM) made a suitable breakout board for $50 then I would absolutely choose that. That's less than a drop in a bucket compared to the cost of the overall product.
