Texas Instruments UCC28730QDRQ1 | Demoboard PMP22288
15-W flyback reference design for automotive inverter power
Overview
| Topology | Flyback Converter |
| Input voltage | 40-550 V |
| Output 1 | 15 V / 1 A |
| IC revision | A |
Description
This reference design uses the UCC28730-Q1 flyback controller to produce an isolated 15-V output. The design is capable of 0.33 A from a 40-V to 250-Vdc input and 1 A from a 250-V to 550-Vdc input. This power system is designed for an inverter bias supply application and is an automotive-qualified solution.
Features
- Wide 40-V to 550-V input voltage range
- Isolated 15-V output with 1-A maximum current
- Peak efficiency of 86%
- Automotive-qualified solution
Typical applications
- Inverter & motor control
