Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
Hola, ¿Me podéis ayudar con mi problema? Cuando conecto la realimentación del optoacoplador a RFmax el transformador hace ruido, se regula correctamente la tensión pero el transformador hace ruido. He variado los valores de Rfmin y Rfmax, también los...
Is it possible to start either of these Vipers up earlier than their stated HV startup voltage by sourcing VCC manually (external supply) from the Vin voltage?
Hello, I am currently reviewing your design guide.Could you share the BOM and PCB Layout for this guide?I am interested in the information regarding the part labeled as U1 in the document.
Hi,Trying to develop a board that provide power to a tablet, charger, and the tablet manage the device connected to board.If don't wrong STUSB4500 manage the power flow using CCx lines and over D+, D-, Vbus and GND the device "talk" with tablet and h...
Hello,I am using the STUSB4710 as a PD-Source in my project and have a few questions regarding its configuration. In my setup, I have not utilized the feedback configuration. Instead, I am connecting the PDO outputs of the STUSB4710 to a microcontrol...
Hi, can anybody tell me what type of diode I see here?Marking (see photo) is:ST 6LEZ 904 Board are used for recuperator motor control. Thanks
Hi, I am analyzing the different diagnostics capabilities of VNF1048 eFUSE.Could anyone share some details on how the Short to Battery and Open Load detection can be done for VNF1048 eFUSE output.Is there any external circuit required to detect the ...
Hi all， STTH110，the role of the diode in the two-tube forward circuit is the demagnetization of the transformer, which is found to burst in use. The diode is exploded in the middle, pictured below: The question is how did the diode break? The ...
Hi all,I selected the L6981C50DR for my DC DC buck converter with the following external components and schematic for my application:Cin: GRT31CR61H106KE01L Multilayer Ceramic Capacitors MLCC - SMD/SMT 10 uF 50 VDC 10% 1206 X5R AEC-Q200 RoHS Complian...
Hi all, I have a problem with the L6924 in the below schematic. After ca. 1 minute of USB power both red and green LED lit and the output keeps on bouncing from 0 to 4.6V with or without battery attached. The 5V USB are stable and so is the charger...
