Isolated bias supply reference design using PSR flyback topology with planar transformer
PMP41175
概覽
This reference design is a tiny three channel isolated bias supply based on Flyback topology. Providing the voltage supply for isolated gate drivers is a typically use case. The design integrates three 21V, 2W isolated outputs and one 7V non- isolated auxiliary output. The design uses a planar transformer integrated into the printed circuit board (PCB) to reduce the board height and system cost. The LM5158-Q1 converter supports primary-side regulation (PSR) by using an auxiliary winding on the primary side. The maximum efficiency is 88%.
特點
- Primary-side regulated flyback for three outputs (21V, 2W) with planar transformer
- Peak efficiency 88% at 6W full load
- Low transformer Parasitic capacitance (<10pF)
- Low height (9mm)
- Compact size in 50mm × 29mm
