Other Parts Discussed in Thread: UCC28810
Hello guys,
One of my customers is considering using UCC28811 for their new LED lighting products.
Also they are going to start the product design with the following application note.
The PWM and Analog Dimming Solution to Implement 0.05% to 100% Dimming Range
Based on UCC28810/11 Constant Current Buck (SLUA701)
https://www.tij.co.jp/jp/lit/an/slua701/slua701.pdf
They have a few questions about UCC28811 as the following.
Could you please give me your reply?
Q1. Do you have any variation data of parameter "EAOUT high" of VOLTAGE AMPLIFIER(VSENSE) section in the electrical characteristics?
Q2. Do you have any variation data of parameter "Maximum current sense threshold voltage" of CURRENT SENSE COMPARATOR section in the electrical characteristics?
Q3. Is there any relation between "EAOUT" and "Maximum current sense threshold voltage"
For example, if one device "EAOUT" is 5.5V, is "Maximum current sense threshold voltage" of the device trended toward higher voltage (1.8V side)?
Or if one device "EAOUT" is 4.5V, is "Maximum current sense threshold voltage" of the device trended toward higher voltage (1.8V side)?
Or is there no relation between those?
Your reply would be much appreciated.
Best regards,
Kazuya.
