Part Number: LM25010 Output voltage of LM25010 regulator rises when load is applied. How can this be explained and corrected?
Vin: 32VDC
Intended Vout: 16.8VDC
Test conditions:
No load: Vout = 17.05V, Vfb = 2.538V
330ohm load: Vout = 18.13V, Vfb = 2.…
Part Number: LM25010 Hi,
we are using LM25010SDX/NOPB switch mode regulator for 19 to 30 V input and output max of 300mA/5Volts.
refer below our schematic.
As per calculation we estimating the peak current in inductor is 330mA. so we using 570mA inductor…
Part Number: LM25010 Other Parts Discussed in Thread: LMR14030 Hi all,
I'm looking for a pin-to-pin compatible device for the LM25010 which is able to support up to 2.4A of output current. Point is that it is not possible to modify the PCB for convenience…
Part Number: LM25010 Max Junction temperature for both is 150 and is calculated from ambient + power (assume max 1amps times 5 volts=5watts) times 36. without adding any ambient temperature the temperature is already above maximum
What am I missing
Thank…
Part Number: LM25010 Hello All,
I am using this IC for an output of 9.6V with 0.1% resistor divider for setting the output to the mentioned voltage.
1st time run gave a result of 9.5V which was acceptable. But from the 2nd run it started giving an output…
Part Number: LM25010-Q1 Other Parts Discussed in Thread: LM25010 Hello,
I am using LM25010 DC to DC converter IC in one of our board.
in efficiency i seeing different behavior at low current mode. efficiency of the SMPS is less at low current. is that…
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 this data…
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= 13V with…
