Other Parts Discussed in Thread: LM26001 , LM26001-Q1 I would like to confirm off-pulse skipping operation.
I understand off-pulse skipping operate when the input voltage is falling down and approaches the nominal output voltage.
Is this correct?
And when…
I would like to confirm the characteristics.
In Figure 14, there is the data. For normal operation, the current is "1A", and for sleep mode, the current is "40mA".
I have a question for normal operation.
1. Is the dropout voltage …
Other Parts Discussed in Thread: LM26001-Q1 , LM26001 I would like to know the minimum input voltage for LM26001-Q1.
The customer wants the fomula for the minimum input voltage( when they set output voltage 5V).
Could you please provide the formula for…
Part Number: LM26001B Other Parts Discussed in Thread: LM26001 I'm desiging a multi-layer board which include LM26001B.The board is 4 layer. 1:Sig/LM26001 2:GND 3:POWER 4:Sig/No components
In the powerlayer, may I route Vin or Vout under the switching…
Hi Oguri-san
According to the block diagram, it is triggered as soon as FB goes below 0.9V, regardless of the current. Another form of frequency foldback happens when the part is in sleep mode (COMP voltage is low). I cannot fully explain the behavior…
Greg,
From what you have written above, you said you have not been "able to repeat the issue once it is cleared on the three boards." Does this mean they are "ticking" away correctly now?
As far as additional FW checks are concerned…
Other Parts Discussed in Thread: LM26001 , TPS54140 Hello,
I'm looking for a PSPICE model of the LM26001Q. I saw there is a model for the LM26001 but when I download it and import on PSpice, the model component has only 5 pins (instead of 17pins, according…
Hi,
You might also want to look at the LM26001. It has a very low IQ and an input voltage range that meets your customers specifications.
LM26001Q is an Automotive Grade product that is AECQ100
grade 1 qualified (-40°C to +125°C operating…
