So I've made a shitty camp light out of a 12v strip of led's, a buck boost converter, and a micro usb port. The port connects to my powerbank which outputs 5v 2.1A. I'm having a problem where the chip on the buck boost board (circled) is getting really hot really quickly. How can I stop this? Reduce current into the board with a resistor? Or do I just have to add a heatsink to the chip?
