Part Number: LM5160A Hi,
Following is described on the datasheet p.13;
"The minimum load current for continuous conduction mode is one-half the inductor’s ripple current amplitude."
Why is this restriction existed?
How is the device behavior…
Part Number: LM5160A Hi,
Following is described on the datasheet p.24;
"The primary-side output voltage of a Fly-Buck converter must be no more than one half of the minimum input voltage."
Why is this restriction existed?

Part Number: LM5160A Dear Team,
My customer is planing to use VOUT(PRI) to provide power to VCC pin.
Is there any concern here?
Will the load not enough, cause output unstable?
Besides, they will design Vout(pri)=10V, Vout(sec)=5.6V.
What is the suggested…
Part Number: LM5160A Other Parts Discussed in Thread: LM5160 Hello team,
My customer is using the LM5160A and is running into a few issues. The goal is to have a variable power supply that takes +55VDC and very the output from 0 to +48VDC.
A Continuous…
Part Number: LM5160 Hi,
I have designed isolated power supply (+15V and -8V outputs) using LM5160A shown below, the primary output at terminal 3 of the transformer is 7.5V. The FPWM pin is connected to Vcc to get CCM mode, but the IC output is always in…
Part Number: LM5160A hi team,
i am working on a circuit, before it goes to production i checked it and saw a conflict between the design i got from webench and datasheet.
on webench the poles of the transformer i used for isolation are opposite and on…
Part Number: LM5160A Other Parts Discussed in Thread: LM5160 Hi team,
customer use LM5160A for flybuck. the input is 12VDC and output is 5V/1A. there is a problem is that when the load current is 0.8A, output will drop to 4V.
could you help on it？thank…
Hello Tomasz,
The ringing as a result of stronger gate drive currents due to external VCC, is dependent on layout. The layouts between the two boards are likely slightly different (even lead inductance between packages are different) and as a result…
Part Number: LM5160A Hi,
I am considering the following specifications for an isolated power supply. I would like to use the LM5160A device, but is there a reference design with the following specifications? Are there any devices other than the LM5160A…
