It is a question of regulator RHFL 4913.

​It is a question of regulator RHFL 4913.There is a noise graph on the data sheet(DocID10005 Rev17 Figure 37), but there is a peak at 30 kHz.Is RHFL 4913 a switching power supply?If it is not a switching power supply what is the noise of 30 kHz?Thank...

STSPIN250's can I use 3.3V for it's logic pins?

STSPIN250's EN\FAULT and STBY\RESET pins are described as "Logic input 5 V compliant". Does it mean it only supports 5V logic or 3.3V logic will do the job of bringing these pins high?Want to use this device with STM32L496 MCU which is a 3.3 device.

Posted on January 08, 2013 at 01:12I have STEVAL-PC009V2 communication board for the L6470 evaluation purposes. I saw some posts found bugs on either communication board or PC software during the evaluation therefore I went to the website and downlo...

VNQ5E160AK-E (new design) vs. VNQ5160 (old design): can current sense pins stay unconnected (and CS_DIS set to GND via 10k resistor), so the old PCB design can be kept?

We are using VNQ5160 in a project, but those chips are now not avalible and we would replace them with VNQ5E160AK-E. Footprint and switching power is the same, the only main difference is in status pins, where older chip has status outputs and new ha...
