Part Number: LM5060

Tool/software:

Hello,

Equation 6 states that Vout _max = V6 = Vcv_D1_max

Should it not be Vcv_D3_max?

So if I want to clamp at lower voltages to prevent overvoltage on the output I need to adjust this voltage but also take care I can absorb the energy by other means.

Thanks in advance

Best regards,

Sebastian

Hi Sebastian,

Your are correct. it should be D3.

We have newer devices to handle automotive transients conveniently than LM5060-Q1.

Can you share your specs and requirements to suggest suitable device.

Thanks for the info.

I need a protective device running in both 12/24V systems (<90W ) capable of protecting against transients, reverse polarity, unsuppressed load dump, the lot of it. My down stream devices can handle maximum 32V so either by clamping fully below that, turning of the switch controller output fast enough or a subsequent DC/DC with higher input voltage.
