Dear all,

Is there rule about minimum LED current to stable operation?

*Background of question

LM3405 has rule of minimum LED current = 200mA and over to stable operation.

So that, I wonder if TPS92510 has this current rule.

Best regards,

Hello Takao,

The limitation for the LM3405 comes from it being internally compensated. The TPS92510 has COMP pinned out so it can be adjusted, so there really isn't a minimum output current specification as you can make sure it's stable.

Clint
