AC or DC input (ultra-wide input)to DC output SMPS circuit design ?

Dear ST team,​I want to design an SMPS circuit with the following specifications:​​* Input can be either 33-265 VAC or 48-375 VDC (ultra-wide input)​​* Multiple DC outputs​1.output : 24V with 0.7 A​2.output : +10V with 0.8 A​1.output : -10V with 0.8 ...

PM8804 VC high voltage set incorrect voltage level

I’ve build 5 boards using PM8804 and only one board seems to regulate the VC (Output of the internal high voltage start up regulator) according to the datasheet where the high voltage regulated drop below 6V when it detect auxiliary power detected hi...

i have received parts from supplier STN3NF06 however i have 2 different codes showing on the reels The new stock shows STN3NF06LSV1 The old stock show STN3NF06LSF2 i can find no reference to this on any datasheet online. can someone advise here

Hello everyone, I am trying to use the PWD13F60 full bridge driver IC to drive an acoustic transducer. I am using the corresponding evaluation board for test purposes. I have a question about the IC. What exactly is the purpose of the SENSE pins?

I noticed the pads of these pins are very small. I'm a bit worried this is critical with high-current thoughput. For my application current peaks might exceed >5A for couple us. Pads like GND, VS and OUT are very large in comparison..

I am referring to L6491 EVM from ST Microelectronics. It is driving 3 Phase motor MOSFETS. Is there any equivalent isolated motor driver or Can I isolate the PWM signals coming from the uController using optical isolation?

Is this normal behavior for the L6491 Smart Shutdown signal/system?

Using 2xL6491 in a full H-Bridge inverter for a PMDC motor, PWM switching frequency is 32kHz. With the smart SD threshold set low to verify the functionality, we see what appears to be skipped PWM pulses most likely due to the shutdown system blockin...

Hi Community, 1. Do we have any parts similar to LTC3588-2 (comprising both rectifier and boost circuit) for Microwave power harvesting? 2. Is there any product replacement for EFL700A39, currently available to purchase? Thank you in advance.

Hi i Need STPS24045 safety area that diode per channel non repetitive forward current at 28V@200A 1 second durability. Can you share this document or durability data? Best regards

STEVAL-ISA147V3 project source for MCUs.

Hello forum! I purchased the STEVAL-ISA147V3 for evaluation. I am glad to report it powers on and drives a load. However, the code is not up on the product page. Can you please send it?There is an older question on the forum about this, but no reply ...
