Part Number: LM21215A Hello,
My customer would like to the impact of voids on the efficiency, please find below his need:
" This type of TSSOP package can generate a high void rate under the ExposedPAD during the industrialization. In my design…
Other Parts Discussed in Thread: TPS56121 , LM21215 A few years ago, I did a design that had four LM21215A-1 supplies and one TPS56121 supply. A general
board revision prompted me to review the design parameters for all of the supplies. I ran, or rather…
How does PGOOD (power-good) behave when PVIN and AVIN are below 2.95V?
My PVIN is rising slowly, and I need to know at what time it starts to pull low.
Other Parts Discussed in Thread: LM21215A , LM555 , SN74LVC1G14 I have a design that uses multiple LM21215A's to generate a number of low voltages from 5.0V input. I'd
like to reduce the worst-case ripple on the 5V by synchronizing these supplies…
Other Parts Discussed in Thread: LM21215A my college is looking for TINA pspice model of LM21215A or a recommendation for similar one.
I think this is from national semiconductor. It is most possible that there is no such tina model.
I am writing this…
Other Parts Discussed in Thread: TPS56121 , LM10010 , LM21215A Dear Sir/Madam
We have a question about C6678 SmartReflex Power.
On TI's website, we found two solutions for conventional DC-DC power C6678
One is LM10010+TPS56121(PMP7256 Circuit, Does not…
Hello Jimmy,
From a quick search it looks like TPS62867 is pretty comparable to LTC3309B a nd the LM21215A is similar to LTC3311S.
Both have lower switching frequencies than the other devices, but have similar input/output ratings.
You may want to check with…
Joe,
i don't directly support those parts but the caps CC1, CC2, CC3 and resistors RC1 and RC2 are the type 3 compensation components for the LM21215A-1 buck converter. TPS544C25 uses a similar voltage mode control scheme. You will want to follow…
Hi John,
Thanks for the information.
The datasheet of LM10011 has equations while using LM21215A regulator. Also, the GUI (present in the link: t www.ti.com/product/LM10011 ) uses the same regulator LM21215A. Please let me know whether the same formulas…
