Texas Instruments LM5122-Q1 | Demoboard PMP31073
1.44-kW, six-phase interleaved boost converter reference design
Overview
| Topology | Boost Converter |
| Input voltage | 9-16 V |
| Output 1 | 24 V / 60 A |
Description
This reference design showcases an interleaved boost converter controlled by LM5122-Q1, operating from a 9.0-V to 16.0-V input voltage range, generating an output voltage of 24.0 V with a maximum load current of 60.0 A (10.0 A per phase).
Features
- High converter efficiency for minimal components temperature rise
- Can be operated with the higher output power if a higher component temperature rises is acceptable
- Low output voltage ripple (smaller than 1% peak-to-peak) for audio applications
- Low input voltage ripple leads to better EMC
- Modular design which enables easy modification for higher and lower output power by removing or adding phases
Typical applications
- Aftermarket audio amplifier
