Replaces LTC3807EUDC LGSG

10.2V output
10V LGSG Buck Board
power module
It is used to replace the step-down module of 61PE20J, which is more stable and durable.

Use tutorial:
1. Place the step-down board as shown in the figure. The tin in the inductor position is high temperature resistant. Pay attention to the temperature of the soldering iron.
2. Solder the 6 positions of IN-, IN+, FB, SW, HG and LG first. HG is connected to the 4th pin of MOS-Q2, and then turn it on to see if it is normal.
3. If step 2 is normal, please turn off the device at this time, short-circuit J1 on the upper left corner of the step-down board, and connect EN to pin 3 of Q10. Power on to verify whether it is normal.
4. There is a 0Ω resistor in the lower left corner of the step-down board. If 0Ω is in the R7 position, it means the output voltage is 10.2V, if it is in R8, it means the output voltage is 10.5V, if it is in R9, it means the output voltage is 10.8V
5. The factory default is R7 gear, and the user can change it to the required voltage.
warn:
J1 is the EN switch. When J1 is shorted to EN, it starts to work, and when J1 is disconnected from EN, it does not work.
