Adding heatsinks to USB charger boards to see if thermals gets better.

As far as testing goes only the blue board got a small coil and might run warm. The other boards have some reasonable thermals and are high quality boards.

Purple have heatsinks on the diodes, master chip and on the underside to make it easier to fit inside the plastic case. It also absorbe heat aswell so: win win.

Blue board have a oversized heatsink on the coil and the diode have thermal glue on it connecting it to the heatsink. Master chip have a 6 mm heatsink and both heatsinks are thermally separated from each other.

The black board oversized heatsink on the coil BUT it is thermally bonded to the heatsink on the master chip. It might be risky since booth can run really hot. But they will spread heat over 2 heatsinks and ground plane. Looking forward for the results.

EDIT: I forgot to put the CTP01 board in the video. But is a similar board featuring 3 capacitors, 2 chips and a heatsink. Only thing i did with it was to swap the original heatsink with a bigger one (Twice the size mounted on the chip) Stock thermals are 59 °C and after 39.9 °C (Loads are short term and not exactly the same between tests)
