Part Number: LM3281 Hello.
my question is about process technology. after PCB assembly we coverage the components with protection acrylic coating .
after run ALT cycles test at -40C and +85C w/o powering the board we found LM3281 balls was shorting.
The rest…
Part Number: LM3281 Hi Sir,
We have a request about the LM3281YFQR DCDC buck converter.
We have faced the situation when ripple voltage from it interferes with the BLE function of our MCU (STM32WB55RGV6TR from ST). This default ripple shape on 3.3v line…
Part Number: LM3281 Other Parts Discussed in Thread: TPS62082 Hi,
Can you please help me, I'm looking for DC-DC converter replacement for LM3281. This IC is perfect for my wireless application but I can't physically solder the chip on! I don't mind a…

Hi,
I have a WIFI module on-board a processor baseboard. This module is the only 3.3V device on the board and I didnt want to use a dedicated buck circutiry for it since that will increase expenses.
The average current draw is around…
Part Number: LM3281 Hello Team,
the LM3281 since it has very small package it has exposed die on the edges. This make the part more sensible to the red and infrared light range (as mentioned in the datasheet).
Do we have some numbers at which light…
Part Number: LM3281 On pg 15 of the LM3281 datasheet, it states that total effective output capacitance must be 3.4 μF to 9 μF.
Questions:
Can this part be used with loads larger than 9uF?
What are the issues with output capacitances larger than…
Part Number: LM3281 Hi Team,
Good afternoon, my customer is interested in the LM3281 given the use of the small 2.2uF output capacitor. Do we have any graphs of load transient behavior using only the 2.2uF cap?
I noticed on the evaluation board that there…

I have a high-power 6V-18V power source, and will be knocking it down to 5V with a TI TPS65279, which will introduce a ripple at 500kHz (which I will endeavor…
