TPS92512: Flicker when dimming

Conny Do

Part Number: TPS92512

Hi,

I have a design with the TPS92512 and unfortunately it has quite high level of flicker when dimming down lower than 100% duty cycle. I wonder the TPS92512/TPS92512HV can be designed to meet the IEEE PAR1789 standard?

Br,

Hello Conny,

How are you dimming your circuit? It should not have high flicker content when dimming.
