ground pin
fb1 (a7), fb2 (d7), fb3 (g7), fb4 (j7) Four output voltage adjustment pins to which 0.5% accuracy regulator resistors can be connected to GND.
run1 (c6), run2 (f6), run3 (j6), run4 (k7) Four-way enable pin, can be directly connected to the input voltage, can also be connected to an external power supply to control the power module, the minimum enable starting voltage of 1.1V, when the enable voltage is lower than 0.95V, the power supply shutdown. It is recommended that this pin should not be left idle when the enable voltage is greater than 1.2V.

pgood1 (c3), pgood2 (c2), pgood3 (f2), pgood4 (j2)
Fault indication pin, PG=high means VOUT is within the voltage range, PG=low means VOUT is below the specified value. This PGOOD pin can be connected to a 100K resistor to the VO pin, can also be connected to other voltage supply to the PGOOD, when the PGOOD is set to low means that the power module is abnormal (the abnormalities include UV, OV, OC, OT, etc.) If you do not need to indicate the function of the fault, do not add this resistor, PGOOD can be left empty.
VO1 (C4), VO2 (F4), VO3 (J4), VO4 (K5) VO can be used as PG power supply pin, four sets of VO have been connected to four outputs inside the power module respectively, i.e. VO1=VOUT1,VO2=VOUT2, VO3=VOUT3, VO4=VOUT4.
MODE1(B6), MODE2(E6), MODE3(H6), MODE4(L6) The FHT4644L is a vacant pin with no electrical function, and can be connected to any pin. (The FHT4644L's operating frequency and mode can be automatically adjusted to a typical operating frequency of 1MHz.)
SGND (F7) For signal ground, it is recommended that GND (power ground) and SGND be wired separately and eventually connected with a 0 ohm resistor.
SS1 (A6), SS2 (D6), SS3 (G6), SS4 (K6) External soft start pin, external 3.3nF ceramic capacitor can be connected to signal ground, if there is no need to increase the external soft start function, this capacitor can not be added, SS pin is empty.
NC (E7, H7, L7, C7, L5, H5, E5, B5, J3, F3) Empty pin, no electrical function, can be connected to any pin.
