LMR43610-Q1: Could you please help to provide the spec. of VIN sustain to transient?

Part Number: LMR43610-Q1
Other Parts Discussed in Thread: LM61480-Q1

Hello TI,

We are checking the input range of LMR43610-Q1, and wondering if there is a specification of VIN sustained to transient like LM61480-Q1 list in datasheet? Thank you.

LM61480-Q1 datasheet in page.6:

(2) A maximum of 42V can be sustained at this pin for duration of ≤100ms at a duty cycle of ≤0.01%. 36 V can be sustained for the life of this device.

Many thanks,

Peter Wu

    Hi Peter,

     There is no specification of VIN sustained to transient like LM61480-Q1 list in datasheet.

    You can see input range of LMR43610-Q1 as below, absolute maximum input voltage is DC 42V.

    If you care about transient voltage glitch, it is better to put TVS on the input or choose a high input voltage range buck converter.

    Thanks
