TPS92513: Can TPS92513 control the constant output current with 3mA~600mA range by PDIM signal on duty?

Part Number: TPS92513

One of my customers is considering using TPS92513.

At this moment, they have the following question.
Could you please give me your reply?

Q. We want to control the constant output current with 3mA~600mA range by PDIM signal on duty (PDIM frequency = 250Hz)?
Can TPS92513 control it without any problem?

Your reply would be much appreciated.

Best regards,

Kazuya.

Hello Kazuya,

It's recommended to achieve <100:1 dimming ratio when using PWM dimming. I'm afraid 3mA is a little hard to reach. Maybe you can introduce your application and design requirements and I can give some suggestions.

Hello Robin,

Thank you for your reply and I'm sorry to be late may response.
My customer will try to control the output current using both PWM and Analog dimming.

Thank you again and best regards,

Kazuya.
