LM5060EVAL: LM5060EVAL Design Query

Prodigy 45 points
Part Number: LM5060EVAL
Other Parts Discussed in Thread: LM5060, LM5060-Q1

Tool/software:

Dear Team,

We are using LM5060 in our design. I have some doubts when referring the reference design.

Can I know the purpose of D1 and D2.

And what is the voltage of V_Internal.

How the Diode D7 protects the Q3.

And one more DCDC Converter was used in the design to provide the supply for IC when in cold crank conditions.

But in reference design it is stated like the voltage will fall less than 5V during cold crank condition ,in this case how the DCDC converter provide the output of 5V when the input is less than 5V.

    Hi Naveen,

    Thanks for reaching out!

    All these diodes are patches to protect either MOSFET or LM5060-Q1 during transient events. We have newer devices to handle automotive transients conveniently than LM5060-Q1. 

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

    BR,
