Hello,
This is a follow up question to the forum: LM3478: Use boost converter for charging battery with BMS - Power management forum - Power management - TI E2E support forums
I designed a LM3478 Boost Converter with the WeBench. Below are the main specs:
- The design has a Vin of 4-5V and output 7V/2A.
- Charge a LiPO4 battery represented as BATT with resistance of R <= 85mOhms
In simulating the design in Pspice for TI, no errors were found. However, Vout = 3.4702V, I_in = 40.83A, and Iout = -40.83A.
Schematic and transient response are attached below:

Please advise on the corrective steps I must make to ensure accurate functionality of 7V/2A output.
Thank you,
Travis.
