Part Number: LM70880 Other Parts Discussed in Thread: , ISO7041-Q1 Tool/software: Hi,
Is there any Electrical Characteristics difference between LM70880 and LM70880-Q1?
Best regards,
Randy
Hi Nikolai,
You can keep these as DNP. The snubber circuit is there to help you with MOSFET ringing (if you see it is beyond acceptable limits for your design) and the RC in the current sensing path is for filtering any common mode noise - again this…
Part Number: LM70880 Tool/software: Hi,
I am looking for design support for LM70880. I want to use it as a voltage supply for 12V brushed DC motor. I am referring circuit design from datasheet 7.2.2 Design 2. Please confirm to me if I can use this into…
Part Number: LM70880-Q1 Tool/software: Hi
I saw R12 and C22 on the current sense circuit from EVM as below.
What is the purpose of this circuit ?
Thanks

Part Number: LM70880 Tool/software: The design is for a 7.4V/6A buck. When a servo is started, the current will reach 40A (50ms). Will the MOSFET be damaged? Can the short-circuit protection be activated?
Part Number: LM70880-Q1 Other Parts Discussed in Thread: LM70880 Tool/software: Dear TI experts,
My customer did EMC test of their product using LM70880-Q1.
In that test, wide range of frequency (from 40MHz to 150MHz) fail situation is observed. Please…
Part Number: LM70880QEVM Other Parts Discussed in Thread: LM70880
Tool/software:
Hi,
I have some troubles to understand what happens on the LM70880Q1 EVM. I modified the demoboard to set the converter to my final operating point.
Input voltage = 33V …
Part Number: LM70880 Tool/software: There are two thermal resistance numbers on datasheet.
Which one is more realistic on the thermal simulation ?
Thanks,
Moon
Part Number: LM70880 Tool/software: Hello,
My customer found that the LM70880-Q1 has the following Ambient operating temperature specifications:
They want to use LM70880. Can you tell us the ambient operating temperature specification for LM70880?
…
Part Number: LM70880-Q1 Tool/software: Hi,
I have created a custom PCB and used the LM70880-Q1 to achieve an output of 15V and 6A from a 24V power supply. I would like to bring to your attention some issues I have encountered with this component.
Firstly…
