Part Number: LM26001 Other Parts Discussed in Thread: LMR43610-Q1 ,
Tool/software:
Hi,
We are currently working on a vehicle cluster with a focus on low power mode. When the ignition switch is in the OFF position, the cluster enters sleep mode.…
Part Number: LM26001 Other Parts Discussed in Thread: LM5117 Hello,
i got problem with simulation of buck converter LM26001. I used almost exactly values provided by webench and circuit does not behave as expected. I will provide few images and simulation…
Part Number: LM26001 Dear all,
I've designed an embedded system which roughly consist of an microcontroller + External Flash, CAN transciever and the LM26001 buck converter from TI.
During testing of the first prototypes of the embedded system i…
Part Number: LM26001 We have designed in a LM26001. It supplies 5 volts at about 50mA, from a 24 volt power supply. It works most of the time flawlessly, but if power is removed for a short duration, I'm getting a voltage transient that peaks at 23 volts…
Other Parts Discussed in Thread: LM26001 Hi all,
we use the LM26001 for a 5 V supply. At low current we set FPWM mode on, the switcher works than in a discontinued mode. Every 250us some on pulses are seen. This follow-up of the pulses results in a…
Other Parts Discussed in Thread: LM26001 I would like to confirm Pspice model for LM26001.
There is the model of "Average" only. I think it can not simulate transient characteristics.
Is it correct?
If it is correct, how do we simulate transient…
I would like to confirm quiescent current and shutdown current.
The customer wants to know the minimum current;
Quiescent current - Iq Sleep_VB - Iq Sleep_VDD - Iq PWM_VB
Shutdown current - ISD
Could you please estimate (or calculate) them?
…
Other Parts Discussed in Thread: LM26001 I would like to confirm webench for LM26001/26003.
Can we add and remove the component and the line?
The customer wants to edit the circuit and the simulation.
Best regards,
Atsushi Yamauchi
I would like to confirm the current consumption with VIN < VOUT.
In this case, this IC does not operate switching. Is this correct?
And how do we estimate the current consumption?
In this case, the Input current was 1.1mA.
In the case of VIN …
Frank De Stasi,
Thank you for answer, but let me confirm one point.
Does it means MIL based FIT calculation is only applied for system level and not applied for device level ?.
And TI’s method (1.8 for LM26001) is based on Arrhenius model ?
Best…
