Part Number: LM2574HV Other Parts Discussed in Thread: LM2574 , LMR36506 Hello
Is it possible to generate a -15V output voltage with a LM2574-15 as a inverting buck boost regulator?
Thank you
Part Number: LM2574HV Other Parts Discussed in Thread: LM2574 Hello,
I am currently planning on using the LM2574HV adjustable switching regulator to regulate 24V input down to 5V, no more than 0.1A needed on output. However, we also need the ability…
Part Number: LM2574HV Support Path: /Product/Development and troubleshooting/ Hi,
I would like to know at what temperature does LM2574HV thermal shutdown? The datasheet indicates the operating temperature can go up to 125 degree Celsius, but no information…
Part Number: LM2574HV I have a thermal issue with a design circuit which I would like some advice.
The input is 24VDC and will step down to 5VDC via voltage regulator and then to 3.3VDC. I used a DMM and measured that the regulator's input current to…
Other Parts Discussed in Thread: LM2574HV The data sheet for the LM2574HV seems to specify the θja differently in different locations of the data sheet.
The specifications for the DIP package on page 6 and in figure 17 of the data sheet seem to be the…
Based on Webench the device will not do 300mA; and just barely 200mA. However the device junction will get very hot.
It looks like the device is either going into current limit or thermal shutdown or both.
You might want to check the current rating…
Hey Dan,
LM120K-5.0/883 is indeed obsolete. I've attached the PDN.
We don't have an exact P2P replacement so I'd recommend the UA79 series as the closest alternatives.
