Ultra-small 10mm╳10mm DC-DC step-up module based on sx1308

Based on https://oshwhub.com/18511895537/chao-mi-ni-sheng-ya-mu-kuai, this big guy has modified the mini boost module. The switches and LED indicators have been reduced and made smaller.
FANSEA's SX1308 is a current mode boost converter with a fixed frequency, wide input voltage (DC2V~DC24V), a maximum output of DC24V, and a SOT23-6 package. The operating frequency can be up to 1.2MHz, the maximum efficiency can reach 96%, and the peripheral circuit is simple. Built-in soft start circuit.

4V boost 5V 1000ma current efficiency 78% ripple 140mv, maximum temperature 97, 500ma long-term use is no problem, and a heat sink needs to be added for larger currents.
It has been verified by making a board. It is difficult to weld something that is too small. It is best to use a heating table. The no-load current is about 50ua. If you have requirements for ripple, you can add a 220uf solid capacitor to the output, and the ripple can be reduced to 30mv.
