24Vin to 12Vout @ 100mA isolated push-pull reference design with cascode FETs
Details
| Topologie | Gegentaktflusswandler |
| Eingangsspannung | 12 V |
| Ausgang 1 | 5 V / 0.25 A |
| IC-Revision | B |
Beschreibung
This reference design extends the input voltage range on low-voltage push-pull controllers by employing cascode external FETs. The input voltage range is 12 V (+/-10%) or 24 V (+/-10%), with an output power of 1.2 W. The output voltage can be selected from two values, 12 V and 5 V, according to a list of four transformers.
Eigenschaften
- Low-cost solution, allowing high voltage isolation and low noise
- No loop compensation (open loop)
- Typical application: isolated gate driver power supply
Typische Anwendungen
- AC analog input module, Multifunction relay, Processor module, Wired communication modules
