The primary-side regulated (PSR) flyback converter reference design provides dual outputs (12 V at 170 mA and 18 V at 60 mA). The design has a small form factor with low component count. It operates over an input voltage range of 8 V to 28 V to deliver two isolated outputs. Operating without an auxiliary winding or optocoupler, the LM5180 provides very tight output voltage regulation. The LM5180 offers several protection features to ensure protection of the regulator during fault conditions.
