The mps2236 chip has a wide input voltage range and can be input from a 3v-18v power supply. Only when the input voltage is higher than the output voltage can the correct output voltage be obtained. The output continuous current is 6A and the ripple is 30mv-50m. When I measured 4-5A, the ripple The ripple is around 45mv. Since the chip was purchased on Taobao, the chip was not exactly the same as in the design drawing. This may be the reason for the high ripple. The efficiency is around 93%. Due to limited conditions, the dynamic response was not measured, and the test was completed at 4A. Be sure to do anti-reverse protection, if the connection is reversed, it will be burned immediately. Since there is no module reuse, only one is drawn on the PCB.
