Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
Dear STMicroelectronics Technical Support Team,I am writing to request the design files and magnetics calculations for the EVAL-STCH03-45W evaluation board. I am specifically interested in adapting this design for the following input voltage 84-264Va...
Hi,We have designed PFC using L6562 referring application note AN2761 on that the auxiliary winding is used only to sense the zero current detect calc. is in Equation 65 but we also need to power the ic using the same winding.Where can i get that cal...
Hi!I have a couple of questions regarding the STPM01 energy metering circuit:We are using it for measuring currents only with Rogowski coils. (We have 4 circuits on our board).We are not using the voltage measuring, so it is not connected.The microco...
Hello,I purchased a set of Wireless charging evaluation boards (RX & TX) on Mouser.com for $160.The 2 board names are STEVAL-WBC86TX and STEVAL-WLC38RX. I use STSW-WPSTUDIO V1.8.4 software to try to connect to the board from my PC and get access to t...
Good morning, We are evaluating the use of the VNF1048. During the test phase the problem arose that despite the MOS being in the open state we detect a current flow, even if minimal, that for our application must be avoided. From our point of view t...
Dear STMicroelectronics Team, Good day. This is Louie from SnapMagic Search. We create PCB footprints, schematic symbols, and 3D models for electronic components. One of our customers is looking to integrate X-NUCLEO-IHM04A1 into their design and ha...
V SWITCH_MIN (VLXx)is measured below the the absolute maximum rating on datasheet (-0.5V).However this limit is momentary ony (7.2 ns) as shown on the measurement.Usually datasheet specifies the minimum DC limit and minimum limit during transient val...
Hello,I am looking at the STEVAL-ISB027V1 dev board. I see that it is obsolete. That is fine, I am more interested in understanding if this design could be implemented on 6x independent channels of Tx coils. I want to be able to independently control...
Hello, I am strongly considering using the STEVAL-A6986IV3 based design for a 4 channel isolated gate driver power supply. One thing that looked strange in the the schematic was the four ground capacitors Cgnd1,2,3,4 which are 4.7nF 2000V rated. The...
HiI have a question about the conection of VIPER06 module as auxiliary power supply. I Have a power stage PFC with L6562 and two capacitor in series as outuput capacitor. Then, i need a 15V aux power supply. Can i connect the VIPER06 Flyback stage,...
