LM5155: Non-isolated flyback

Guru 11170 points
Part Number: LM5155

Hello E2E,

Please let me know about the LM5155 on non-isolated flyback. When output current load any-mA, output voltage goes to fall, switching operation likes hiccup, the LM5155 stop. The LM5155 did not stop under no load.

Question;
Does TI have any advice on the above issues?
Does LM5155 have blanking time on CS-port when FET-ON switch?

If TI needs the schematic, I will upload it on private message.

Best regards,
ACGUY
