Part Number: LM25576-Q1 Other Parts Discussed in Thread: LM25576 , LM5575EVAL Hello,
I am looking to test the LM25576, but there doesn't seem to be an EVM available on the sample store. I was wondering if anyone knows if an EVM for this device exists…
Part Number: LM25576-Q1 Hi,
the maximum value is mentioned as -1.5V For creating a 5V, SW to GND value will definitely be higher than 0V.
Could you please confirm this value?
David,
I think its just a bug in the drawing package. I ran a sim using the LM5576 (non -Q1) and the schematic connections looked normal. The same bug exists for the LM25576-Q1 but not for the LM25576. I suggest that you run the same sim for the LM5576…
Hi Bryan,
I captured the +/-2.5V rails after removing the 78M05 and powering the 5V board ciruitry from external PS. Refer below scope waveforms before and after removing of the 78M05. Looks like it is not the current limit issue. I am curious to understand…
Hi Divya,
The only suggestion I can find is that several of the logic lines in our evaluation board have a series 50ohm resistor.
For example pins: ADC10D1X00RB.pdf
U3 PDI
V3 PDQ
Y3 FSR
W4 DDRPHASE
B3 ECE
V4 CALDLY
V5 DES
This is to…
Feiran,
looking at the ADC07D1520 EVM schematic, I noticed the FMC pins have connection made on rows besides H, G, D, and C. Therefore, this is HPC connection

Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
Gary,
Most any of our power controllers with dual output capability will provide the control. See attached document starting at page 50 with the dual output controllers on page 53 and 54 and choose what features you want.
Regards,
John
