The integration of the 100-V rated primary side switch within the flyback controller LM5180-Q1 together with the elimination of an auxiliary transformer winding enables a compact solution
Features
- Quasi-resonant boundary conduction mode along with frequency modulation provides peak efficiency of 90% at balanced full load.
- Supplies output power up to 1.2W per IGBT driver.
- Provides compact and cost-effective solution due to elimination of optocoupler and transformer auxiliary winding.
- Provision to turn the power supply on and off through the EN pin.
- Programmable soft start limits the inrush current drawn by the power supply.
