Part Number: TPS92690

Hello guys,

One of my customers is considering using TPS92690 for their new products.
They want to control LED current with IADJ voltage.
At this moment, they have the following questions.
Could you please give me your reply?

Q1. Do you have LED current (Iout) response data when IADJ voltage is changed?
They want to know how long it takes the current to follow after IADJ pin voltage changing.

Q2. According to TPS92690 product folder, TPS92690 Iout maximum current is 5A.
What are VIN/VOUT conditions for this 5A output?
Also how was the 5A calculated?

Your reply would be much appreciated.

Best regards,
Kazuya.

Hello Kazuya,

Q1. The response time of the output current relative to IADJ is dependent on the power stage design, loop BW and the amount of change you are applying to IADJ.

Q2. The TPS92690 is a controller so we listed the 5A as a general recommendation. Being a controller, the output current is dependent on the external components, switching frequency and power stage design,

Thanks Tuan
