- VOUT = (VIN * D)/N
- More suitable for 48V in than for 24V, 100 – 200W
- Optimal utilization of transformer core and primary
winding (one vs. two for push pull)
- Excellent for medium to high power applications

Primary Switches: |
| Universal 48/60V Telecom Bus Input (36-75V) |  |  |
| Reduced Range 48V Telecom Bus Input (36-60V) | | |
| Regulated 48V Telecom Bus Input (43-53V) | | |
| 24V Mobile Comm. Bus Input (18-36V) | |
 |
Secondary Diodes: Fast Recovery Diodes, Schottky Diodes

- Self-drive can not be used for symmetrical
topologies.
- Most common solution is to generate sync
rectification gate drive signals at the primary side
- Generated gate drive signals are sent over to
the secondary via signal transformers
