Part Number: LM25010 I have some serious frequency jitter in the LM25010 control.
Design is attached. All my prototypes (3) have the same problem.
On-time matches what is set by the resistor at the Ron pin but the frequency keeps sweeping.
Vin=…
Part Number: LM25010 We are operating the LM25010 at Vin=24V, Vout=3.3V, Ron=18.7k and L1=22µH. The typical output current is about 50mA.
This results in a switching frequency of about 1.3MHz. The recommended switching frequency is 1MHz.
Do we need…
Part Number: LM25010 Good morning,
our customer has reported following issue: after several weeks of operation, the LM25010 burns out (please, see attached picture).
Nominal power supply: 24V
We don't know the supplied current (we are gathering…
Part Number: LM25010 Other Parts Discussed in Thread: TPS25921A I am currently using LM25010 to generate 5V from 24V. I have a system in which I might have an external 5V power supply and I would like my board to switch over to using the external power…
I have attached the spread sheet, if you try to use the values in the design below, it will tell you its wrong.
Maybe try this link again, it worked for me on two computers, it just takes a while to load

Other Parts Discussed in Thread: LM25010 , LM25011 Hi,
This is my first post in this forum so i'm don't be shure if i am in the rigth place.
I'm worked with a LM25010 and i want to limit the output current, but in datasheet they say if i want to…
The problem was caused by inproper decoupling /layout traces.
The ground from the feedback divider was in the path of the load current - which compromised proper function.
This part is very nice - but needs careful layout.
rgds.
Thank you for using Webench Power Designer. The reason why you are unable to simulate with the WSON package is because it's pin mapping is slightly different from HTSSOP. Despite WSON which is a 10-PIN Package, HTSSOP has 14 PINs (EN for heat dissipation…
Other Parts Discussed in Thread: LM25010 Dear Sir,
I am using Webench designer with the LM25010 switcher IC. It seems perfect but I can not simulate it wih the WSON package, only with the TSSOP.
When I look in the datasheet these package seem to have…
Other Parts Discussed in Thread: LM25010 Hello,
