Texas Instruments UCC28740-Q1 | Demoboard PMP41009 REV A
Automotive ultra low standby, flyback controller with integrated HV startup and optocoupler feedback
Details
| Topologie | Sperrwandler |
| Eingangsspannung | 350-1000 V |
| Ausgang 1 | 14 V |
Beschreibung
This reference design provides isolated 14-V and 56-W outputs with a quasi-resonant flyback topology. The power supply can be powered from the 350-V to 1000-V DC input. This design uses cascode MOSFETs and flyback controller UCC28740-Q1. The line and load regulation are regulated to within ±1% precision. The peak efficiency is 84.6% at 1000-V input and 56-W output.
