TEA1716 based LED driver THD issue

[jitengala]

I am using TEA1716 for 250W LED driver design in which I am getting a THD of >20%. Please suggest the changes to be done in my design to achieve THD < 8% or should I change my IC as TEA1716 operates in DCM which has high peak currents. If you need some more information, please ask.

If you need THD<10%, you could select SSL4120 replace TEA1716 because of SSL4120 focus on LED lighting application.

I am not sure if you could design THD<10% with TEA1716, but only give you some suggestion about improve THD in your products.

1: Improve the PFC then you will get the smaller THD

2: Control your PFC works on BCM
