Hello everybody,I need to user Viper115HS or Viper222XS vith 15V 600mA output at non isolated buck topology. I was designed my Fb pin with 130K Ohm and 11K Ohm resistors. But I can not find right Comp pin configuration. could you write capasitor and ...
Good afternoon ST engineer。I'm developing a DC motor control hardware using the L9945 in H brigde mode 。But facing a problem: the datasheet haven't any description about the Mosfet Pre-driver peak drive current when using external drive resistors...
I have a circuit with pmic STPMIC1APQR and STM32MP157DAA1 processor. For reference, I take STM32MP157A-EV1.There are cases when STPMIC1APQR does not turn on every time you turn on the power (1 time out of 20-50 turns on). At the same time, the input ...
Hello,I have a Nucleo L476RG that I plug onto a PCB that I designed (used as a power input) and to my computer (only used for data transfert).My issue is that I would like to plug both to the Nucleo, but only use the PCB for its power supply.Moreover...
Hi there, I was unable to find any matching for this part below, some bi-directionnal TVS I presume, but "L06" returns nothing.I need your help ^^ thanks.Nicolas.
Hi, i'm trying to power an usb-c device that needs 5v 2A, with a power supply (5v 8A) that doesn't support power delivery. For doing that i tried to use the evaluation board EVAL-SCS002V1 connecting the power supply wires (+ and -) to the green conne...
Hello everybody,I was designed a SMPS with Viper222XS for my project. I need to 400ma current for my project. its start with 100mA at soft start and going to 400mA immidiatly after pushhing run button. But I have some problem at here. SMPS was goes t...
Hi, I would like to know is there any simulation tool for the part VNF1048F?
Hello.I want to control multiple solenoids using multiple FET switches and isolate all these solenoids from the circuit in case of trouble using large FET switches.But I got into trouble looking at the specs. I don't know how long the IC can withstan...
I am using Viper27HD integrated circuit. RC snubber structure is not recommended for the diode in the secondary output on the datasheet and edesignsuite.Resonance occurs between the secondary leakage inductance of the transformer and the parasitic ca...
