Overview
| Topology | SEPIC Buck-Boost Topology |
| Input voltage | 46-60 V |
| Output 1 | 110 V / 5 A |
| IC revision | A |
Description
This 500-W interleaved SEPIC converter reference design supplies a non-isolated adjustable 5 V to 110 V output voltage with a maximum output current of 5 A. The main power stage uses two LM5122 controllers to power the primary and secondary phases of the SEPIC. A LM5007 buck converter is used to generate a local 10 V bias.
Features
Interleaved power stages reduces output capacitance1-V peak-to-peak ripple at full load with output voltage of 110-VAchieves over 96% efficiency above 500-W loading across input voltage range
Typical applications
- 12-V, 24-V, and 48-V Power Systems
- Automotive Start-Stop
- High-Current Boost Power Supply
- Audio Power Supply
