VIPER26L compatibility with VIPER26K

Hi, we are using VIPER26LDTR in a non-isolated AC/DC converter with 220V AC line input and 16V DC output. Can we replace the chip with VIPER26K version without changing the circuit/PCB? The K version has a MOSFET capable to withstand 1050V but apart ...

L4931CD33-TR Hello, please could anyone clarify the requirements for the Inhibit pin? The datasheet isn't clear, should Inhibit be left floating or grounded for output enabled?

Hello, We are going to develop a 3 phase interleaved PFC for 30kW. I want to apply STNRGPF01, but it is marked as NRND. I wonder if there is any reason why it should not be used or discontinued.

If there is a clear reason for not being used, can you recommend another part?We can't do fully digital programming.

H2PAK-2 vs H2PAK-6 MOSFET package for high current application

I'm using multiple MOSFET of STH310N10F7 in parallel for current of approximately 60A.MOSFET are used in DC Bias and not switching so time delay is not a factor of consideration.I'm confused between the packages.What are intended application of H2PAK...

Beginners question: IHM01A1 + Stepper - What am I doing wrong

I am an owner of the STEVAL-EDUKIT, an inverted pendulum kit by ST with an NUCLEO-F401RE, IHM01A1, Nema17 motor and an rotary encoder + a 2A, 12V power supply. I have no prior experience with motor control whatsoever. See https://www.st.com/content/s...

Which pin is used as output for connecting load on spv1050 ? i need to connect load .

i am trying to charge li ion battery. the power should be available all the time , even if there is no harvesting in process.#Spv1050​ 

IHM01A1 Shield project - How to create from scratch?

I am using a IHM01A1 Stepper motor shield with an STM32F401. The provided example for one motor from the X-CUBE-SPN1 package works as expected and I can properly control the motor.Now I want to basically recreate the project from scratch as a prober ...
