LM74502H-Q1: Designing with LM74502QDDFRQ1

Part Number: LM74502H-Q1
Other Parts Discussed in Thread: LM74502

Tool/software:

Hello Team,
We are using the IC LM74502QDDFRQ1 for one of our applications.
Can you please verify the circuit?.

The OVP set is 13.75V.
The MOSFET we are using is IPTC011N08NM5ATMA1.
The maximum continuous current is 10A.

Hi Sv,

What is the power source? Do you expect any kinds of transients? This is to know the need of any TVS at the input.

Rest, the design looks fine.

Hello Shiven,
Thank you for your reply.
The input will be from an DC DC converter RPL-10-T.

The maximum load will be just above 5A and the load will be some LEDs.

Hi SV,

Is RPL-10-T going to be at the input of the controller i.e VS?

Looks like this can output up to 5.5V only and not 12V.

Just to re-check, RPL-10-T will be connected at A or B?

Sorry My mistake,
The adapter AEJ160PS12 will be used at the input of the IC.
We have this DC DC converter at the output of LM74502

Hi SV,

I am unsure if a DC supply will have any transients.

If you are aware of any, please let me know.

The design looks fine.
