Other Parts Discussed in Thread: UCD3138
Customer is comparing UCD3138A to XDPP1100 (link below) and has a question regarding flux balancing functionality.
1. Per my understanding, UCD3138A can achieve transformer flux balancing by setting EADC in peak current mode. Is it additionally achieved by PID filter? May I ask more detail on how to implement it? I thought the current mode control inherently was able to control the flux imbalance as the pulse is being terminated at the same peak current by adjusting the pulse width.
2. XDPP1100 supports flux balancing feature in voltage mode using PI filter. Please see 18.104.22.168 in the application note below. I eventually wonder this feature can also be implemented using PID filters in UCD3138A.
Thank you for your kind help.
