Texas Instruments LM5021-2 | Demoboard PMP8586
Isolated Non-synchronous Flyback Converts Universal Vin to 18V@550mA Reference Design
Details
| Topologie | Sperrwandler |
| Eingangsspannung | 90-275 V |
| Ausgang 1 | 18 V / 0.55 A |
| IC-Revision | A |
Beschreibung
The LM5021-2 is an off-line controller that can work in CCM and DCM. A pulse skip mode improves the efficiency of this isolated flyback, and flattens the curve at most loads. It is also suitable for power line communication PSU.
Eigenschaften
- Ability for the power supply to work in both CCM and DCM mode
- Wide Vin capability (90 to 275V AC)
- Duty cycle restriction to 80%
- 84% full load efficiency and over a wide range of load
- Gives the user the flexibility to do external slope compensation with LM5021-2
