Part Number: LM5019
Hello everyone,
I’m currently testing the LM5019 as a buck converter. The desired output voltage is 15V, and the input voltage range is 18V to 50V. The maximum output current is 60mW.
I used the Excel calculator provided on the…
Part Number: LM5019 1. Whether the LM5019 will be damaged if the VCC voltage exceeds 13 out of spec rang.
2.Whether the LM5019 will be damaged if the input voltage falls back quickly and the output voltage falls back slowly, then the SW voltage be higher…
Part Number: LM5019 We are using LM5019 in one of our designs. Voltage at Vfb is showing as 1.288V and Output voltage measured is 3.462 V. Required output voltage is 3.3V.
Please let us know what could be the issue?

Part Number: LM5019 Hi,
LM5019,Modify the resistance of RON(PIN4), but the frequency does not change ,Is the frequency fixed? No load and full load,frequency does not change.
Part Number: LM5019 Other Parts Discussed in Thread: LM34925 ,
Hi Team, It seems LM5019 and LM34925 is similar device but I believe the difference is the following. Is my understanding correct? - LM34925 is recommended for isolated fly-buck converter…
Part Number: LM5019 Other Parts Discussed in Thread: LM5017 , Hello E2E,
May I have your support to take a look whether customer could directly replace lm5017 by using lm5019 on PMP7383 reference design?
Customer only require 3v3/0.1A at isolated…
Part Number: LM5019 Hello,
There is a efficiency graph in figure 1 of datasheet. When 48Vin 100mAoutput, we can read the efficiency is around 80%.
In this configuration, how much efficiency is varied? We care about power consumption so we would like…
Part Number: LM5019 Dear, Sir.
LM5019 is a syncronous buck converter. My customer is concerning the high & low side
cross condution under abnormal condition. So I would like to confirm followings;
Please give your advice.
1. Does LM5019 have…
Part Number: LM5019 Hi team.
My customer wants to apply the LM5019's bootstrap capacitor to 470pF.
Does the problem occur when the bootstrap capacitor is applied below 10nF ?
The System condition is input voltage 54V and the output voltage 3.3V…
