MP2451 circuit debugging notes
- There is an 8V regulator tube inside EN pin, so R5 is not necessary in the circuit, and R2 takes 124K to connect to VIN pin.
- C7 is 100nF, C8 should be selected according to different output voltages, and the value is 33pF for 3.3V output
- The values of C7 and C8 are wrong, the ripple will be large
