Dear Harish,
Mariusz will apply your suggestions and provide results shortly. Meanwhile I have made some modifications on another DUT#3, on R12 (0R5) and R14||R15 (R14 removed, R14||R15=53k5), added Zener 15V shunt at VDD, added 5R1 in series at VDD and…
Hi Nishanth,
The best solution here is to use isolated flyback to create an intermediate voltage like 20-24V. Then use a dedicated battery charger IC like BQ25792 to handle the charging algorithm.
One example that can be used for the AC/DC solution is …
