Part Number: LM26420 Other Parts Discussed in Thread: TPS62442
Hello Sir,
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…
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 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 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 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.
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 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 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…
