  • Hello! I would like to add a load sharing circuit to this board in order to use a LiPo battery as a backup battery. I've found this load sharing circuit. Do you see any problems in adding the load sharing circuit (Q1, D1 and R2 in my diagram) before the VIN pin of PAM2401? So that when USB power is applied the VIN pin of PAM2401 will be VUSB - VD1 (drop over D1) and when USB power is off the VIN pin of PAM2401 will be VBAT - VSD (drop over Q1). In both cases, my output (PAM2401 output) would be regulated to 5V. Is that correct? Thanks!

No public wish lists :(
