Output value of each pin of LM5021-1

Dear, All

In designing a circuit, a customer wants to know the variation between devices.
Please let me know a MIN / MAX value at a given temperature.
a. COMP pin
"COMP Open Circuit Voltage"
- "Min/Max" value when Tj=-40℃.
- "Min/Max" value when Tj=25℃.
- "Min/Max" value when Tj=125℃.
b. Vcc pin
"VCC regulated output"
- "Min/Max" value when Tj=-40℃.
- "Min/Max" value when Tj=25℃.
- "Min/Max" value when Tj=125℃.

Moreover, please let me know the variation in a circuit below.
(It OK with a design value.)
c. Leading Edge Blanking time
- min/max value (Operating junction temperature range)
d. PWM COMPARATOR Block to OUT pin delay in "Simplified Block Diagram"
- min/max value (Operating junction temperature range)

Thanks, Masami M.

    Masami,

     I don't have the data able to give you each parameter at each  temperature, I can provide you the typical range over the operating temperature  of -40V to +125C, where +25C is the typical value.

    a. From the data sheet 4.2V min, 5.1V typ, 6.0V max

    b. From the data sheet 8.0Vmin, 8.5V typ, 9.0V max

    c.LEB 77ns min, 90ns typ, 110ns max

    d.PWM delay 11ns min, 20ns typ, 30ns max
