Our product line only supports the buck converters LM26420 and TPS62441. For support on the other devices like TPS6141 and controllers, please make separate threads with the correct name of the converter in the title, so that the thread goes to…
Part Number: LM26420 Ladies and gentlemen,
I'm currently using LM26420Q1 in my design and wondering if I can parallel the outputs of the same output voltage to have higher current output to the load. My intention was using 2 separate but the same value…
Part Number: LM26420-Q1 Thanks for your support
After the chip returned to normal temperature after a low temperature test, the chip failed.
The output voltage is less than 100mV.
The resistance between sw to GND is 5 ohm.
We guess the lower MOS is short…

I am using a Dual buck converter IC LM26420YMH/NOPB to get 3.3V and 1.2V DC from 5VDC input.
3.3V & 1.2VDC The output looks unhealthy,
Initially, Outputs are varying random…

My circuit using LM26420-Q1, designed a way to output 3.3 V, the input is 5v, often there are veneer LM26420 SW pin resistance 4Ω or so (still work, only LM26420 extremely hot) or to…
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…
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…
Part Number: LM26420 I'm looking to use the LM26420 in a design. The input voltage will be from 3.0V to 4.2V and I would like the output voltage to be 3.3V. Will this part work for my design requirements?
Part Number: LM26420-Q1 Hi,
Need a review on LM26420Q1XMHX/NOPB part.
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…
