Other Parts Discussed in Thread: TIDA-00381
Nice to talk with you!
My customer meet a question about UCD3138. They design LLC with UCD3138 based on reference design: TIDA-00381. Different from initial TIDA-00381 project, they change some conditions:
1. Change frequency range: 150kHz-500kHz
2. Change dead time: 100ns
3. Close all interrupt in addition to CIMINT_ALL_PWM2_COMP
4. Only run voltage close loop
The question is: when Vout jumps from 1.5V to 0.4V(fs=150kHz-500kHz), the full-bridge upper and lower MOSFET tubes in primary side are connected at the same time.
Could you pls give some comments here? If it makes sense we set 150kHz-500kHz here?
