Part Number: LM26420 Hey team,
The LM26420 has a Vref accuracy of 1.5% (I assume this is +/-1.5%, correct?) - so if you are using a +/- 1% resistor to set the feedback voltage, what is the output voltage tolerance?
Our formula would look something like…
Hi,
That's great! This was explained in the App note shared earlier.
I will go ahead and close the thread. Please hit ' Resolved ' if you agree.

Part Number: LM26420-Q1 Hello,
When EN1/EN2 goes Low, what behavior is expected for PG1/PG2? If the Vout is still high enough, will PG1/PG2 keep high even if EN1/EN2=Low? Ot will it be Low immediately when EN1/EN2 goes Low regardless of FB1/FB2 voltage…
Hi Brenton ,
Do you need any further support on this issue? If not, I will go ahead and close this thread. Please feel free to reopen this thread if you have further questions.

Part Number: LM26420-Q1 Hi,
Need a review on LM26420Q1XMHX/NOPB part.
Vin -5V
Vout1 - 3.3V
Vout2 - 1.2V
Fsw - 2.2MHz
Iout1 - 1.21A
Iout2 - 1A
Based on above details, I have updated those values in webench, Inductor values shows as 3.3uH. But as per manual…
Part Number: LM26420-Q1 Hi Everyone,
LM26420-Q1 has 2 voltage outputs.
I am planning to use the part with MPN: " LM26420Q1XMH/NOPB "
Pl. suggest me whether I can short 2 outputs, so as to cater the high load (which is >2A)?
If YES, any caution…
Part Number: LM26420-Q1 Hi
I want to ask about the discharge time of DC/DC converter LM26420-Q1.
For example, if the 2.2V output voltage will drop when the enable signal of the DCDC power supply is turned off,
then I want to know how to calculate the…
Part Number: LM26420-Q1 Tool/software: WEBENCH® Design Tools Hi,
I want to do simualtion on LM26420 , but there is no any simulation model and no webench support, who can provide me the simulation model or alternative simulation model,thanks!
Part Number: LM26420-Q1 Tool/software: WEBENCH® Design Tools Hi,
I used LM26420-Q1 as dual step-down DC/DC converter with 1.8V & 3.3V output voltage. I have problem of efficiency (60%) with the outpout voltage 2 (1.8V) !!
