LM21212-1: Behaviour of LM21212 in environmental stress

Catherine Q.
Prodigy 40 points

Part Number: LM21212-1
Other Parts Discussed in Thread: TPS62873-Q1

Hello Team,

How will the device behave if environmental conditions degrade range specified in the datasheet for the following parameters : Vuvlo and Vuvlohys ?

I mean how will LM21212 behave if AVIN Under Voltage Lockout is below 2.45V or above 2.95V ? In the same way for AVIN Under Voltage Lockout Hysteresis ?

At what range would it have an impact on the device ?

Regards,

Catherine

    Hi Catherine,

    I'm not sure that I understand your question.  We specify that Vuvlo will be between 2.45V and 2.95V for each and every device.  Do you want to change this range?

    As well, please have a look at the newer, smaller, cheaper TPS62873-Q1 as a batter solution.
