Hi Andreas,
Thank you for the reply.
Unfortunately due to the nature of our issue, with current stock being affected, we have had to move ahead with rework and replace the LM3671 with LM3670. If necessary we will re-layout this circuit of the PCB to factor…
Part Number: LM3670 According the the datasheet the maximum output voltage over the full specified operating temperature range should be 1.2 V + 4% = 1.248 V but the voltage measured at room temperature is very close to 1.33 V. This part is used for around…
Part Number: LM3670 I've inherited a design that has two LM3670MF-ADJ set to 3.3V output. I noticed in the datasheet, the 3.3V is outside of the adjustment specifications. However, we're far enough in the design process that the general consensus…
Part Number: LM3670MF-1.8EV Hi,
We are planing to use LM3670 in one of our designs for power solution with 3.6V input and 1.8V output with max 300mA.
But this is a space constrained board. We can not use the inductor's suggested in data sheet. Is it possible…
Part Number: LM3670
Team,
Customer need a precise Vout (fluctuation < 0.1% Vout) at low load for his application: Vin: 5V, Vout: 3.3V, Iout typ: between 70mA to 85mA, Iout max: 200mA
-Do we have some more precise measurements for the PFM to PWM transition…
Part Number: LM3670 We have used the 3.3V fixed version of the LM3670 in our application and have an issue with the device being damaged due to back-power, i.e. if we have no voltage present on the input due to the batteries being removed and the output…
Part Number: LM3670 Other Parts Discussed in Thread: LM3674 , LM3671 , TPS62200 , TPS62240 , TPS62203 , TPS62260 , TINA-TI
Team,
The LM3670MF-3.3/NOPB shows a Vout 3.3V fluctuation of +/-20mV at Vin: 5V, Iout=70mA. However for this application it is required…
Part Number: LM3671 Hi everyone!
I want to know if the input stage of EN (enable pin) will exhibit an increase in quiescent current consumption if it's voltage is significantly lower than VIN. I have performed an experiment with VIN = 3.6V and EN = 1…
Other Parts Discussed in Thread: LM3670 I'm seeing instability in my circuit based on LM3670 1.8V. Sometimes it comes up and it's oscillation decays. (yellow is input)
Other times it goes into oscillation:
Here is what my schematic looks like…
Hi Leon, unfortunately this may be associated with "mask" option. That is when mask(s) are changed to realize another voltage option it may involve the feedback resistor hookup, compensation components hookup, and possible other current and voltage protection…
