Part Number: LM26420-Q1 Other Parts Discussed in Thread: TPS62442-Q1 Tool/software: I am working with the DC/DC converter LM26420Q1XMHX/NOPB. I need a converter similar to this one with two inputs and the two channels are independent.
Part Number: LM26420-Q1 Other Parts Discussed in Thread: TPS62442-Q1 Greetings,
When I run this part through Webench , with 3.3v input, 1.0v out and 0.7amps, the phase margin drops below 35 and Webench fails with, " Design update failed. This design…
Part Number: LM26420-Q1 Hi Team,
Could you possible hlep to share if we have dual channel device which could support 3.3V input voltage, and ≥ 2.5A for each output channel, output voltage should 1.1V and 1.8V. Thanks a lot for your support to recommend…
Hello again Excel,
Below I detail the methodology carried out in the copper track routing process.
Schematic:
PCB Design:
VSS_GND signal: This signal has got mini-planes of copper in the bottom layer "B.CU" (LM26420-Q1 is located in this…

LM26420-Q1.
Our product uses two LM26420-Q1. When we separately measure the static current of LM26420-Q1, the sum of the static current of VINC and VIND is 24mA, which is basically close…
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…
Part Number: LM26420-Q1 Other Parts Discussed in Thread: LM26420 , dear
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-Q1 Other Parts Discussed in Thread: LM26420 , Hi LM26420-Q1 When testing the output SW of LM26420, the test found that the SW waveform overshoot and undershoot are very serious, the undershoot reaches 1.05V, the overshoot is 0.7V, the…
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-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…
