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?
Schematics of LM5019.
R9 is replaced…
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: 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 channel…
Hi,
Normally, webench result is verified with bench.
I did not work on the product development on this specific part, therefore i did not know how far they differ between bench and webench.
I would say that you can test your design in the EVM and see…
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 the…
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 only. -…
Part Number: LM5019 Other Parts Discussed in Thread: TPS23861 , Dear sirs,
I am making a application boad using LM5019 for supplying isolated 3.3v for TPS23861.
I followed same schematics as TPS23861EVM-613;
My schematic is as followw;
The values of L…
HI
Both part have similar performance except OCP point, LM34925 can be replace directly by LM5019, for LM5018 customer need to taking care whether inductor will saturation in OCP statues.
