Texas Instruments LM5007 | Demoboard PMP23320
LM5007 75-V, 0.5-A DC/DC Buck Converter With 80-V Integrated Power MOSFET
Overview
| Topology | Buck Converter |
| Input voltage | 45-60 V |
| Output 1 | 10 V |
| 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 capacitance
- 1-V peak-to-peak ripple at full load with output voltage of 110-V
- Achieves over 96% efficiency above 500-W loading across input voltage range
Typical applications
- Non-Isolated DC/DC Buck Regulator, Secondary High-Voltage Post Regulator
- 48-V Automotive Systems
