To reduce the volume of isolated DC-DC converters using bulky transformers and signal isolators for the gate drivers, a compact single input, six isolated output DC-DC converter using a single PCB transformer for both power and signal transfer is proposed. The proposed sensing for TX input power control prevents efficiency degradation even when subjected to large common-mode transient (CMT) without signal isolators. Fabricated in 180 nm BCD process, the proposed converter with >3 kV isolation and 314 mm3 per output achieved 67% efficiency and CMTI of +175/−167 kV/μs at single 5 V input, six 15 V isolated outputs, and 4.5 W total power. |
