Part Number: LM5119 Hello,
We would like to use LM5119 for inverting buck boost solution. The conditions are , Vin=48V, Vout=-10V, 4A*2. Then I have some questions.
(1) Can we use this device for this requirement? or, can we use this device for single output…
Part Number: PMP7819 Hello,
In the LM5119 reference design PMP7819, there are four 2DB1694-7 as Q9~Q12. Could you please let me know the role of these transistors? I think that the transistor was making faster falling speed of Low Side FET for efficiency…
Hi,I am a student in China. I have chosen LM5119 as my control chip in an interleaved buck circuit. The driving waveform (square wave) can maintain about only 10 seconds or even longer. Then the waveform disappears ,but the level of VCC is still 7.6V…

Part Number: LM5119 Hello,
I am looking at using the LM5119 in an application with dual 24VDC 4A (100W) outputs. We want to create a single PCB assembly which can be figured with jumpers for two seperate 4A channels, or a single 8A channel.
What's not…
Other Parts Discussed in Thread: LM5119 Hi
How can we estimate the accuracy(or ratio) of current at each phase if LM5119 is used by current sharing?
It may flows same current at each phase ideally. However it does not actually.

I am glad to receive your letter.I found a method to prove the pspice model is wrong.I use the LM25119 pspice model and i found the same problem with aamir sheikh Now my problem is been solved. I found the Agnd pin must be in serids with a resistance…
