eDesignSuite. Power Supply Design Tool
Hi!Faced with error "'int' object is not subscriptable" problem while trying to add private diode.Besides, are there any documents on how the Supply Design Tool calculate losses at transformers?
SCT040W120G3AG Spice model incomplete
The SPICE model file for the product SCT040W120G3AG downloaded from the official website is incomplete, it only has the LIB format file. Can someone provide me with the complete SPICE model file? Thank you!
wireless power transfer
Hello experts!my GP is to design an offline DC/DC converter ( LLC ) for cordless home applainces similar to the attached file, now I am aware of how to design LLC for conventional Chargers (wired) to some extent, but i get compeletly confused when i...
Designing High PF AC-DC conveter
We were designing 24v 1.5 Amp smps using l6562 referring application note AN1059 fig 16. getting the 24 output but fluctuating when load is connected and without load power factor is 1.00 and with load it drops down to 0.2 PF and which configuration ...
Rise/Fall Time Issue with STW3N170 in H-Bridge to test High dv/dt test setup for our sensor using driver used UCC21330
I'm using MOSFET STW3N170 in an H-Bridge configuration along with TI’s gate driver UCC21330. During testing, observed an issue with the switching speed as the test is for high dv/dt Observed Behavior: Rise time ≈ 5 µsFall time ≈ 5 µs Test Conditions...
In the SPI protocol of L9305, how is the cnt bit of bit21 used
Hi, There is no specific writing description for the cnt bit in the manual.I guess it's the first time I've powered on and written 1. If I reset the chip through the reset pin, should the cnt be written to 1 after the reset or keep the negation of th...
STP08CP05TTR: Clarification on Using External Current Control for LED Dimming
Hi Sir,We have connected the REXT resistor with a value of 241 Ohms, which sets the current to 80 mA. I would like to confirm whether it is possible to use an external current control circuit to dim the LED.For example, in the case of STP08CP05TTR, w...
STEF01 VCC/GND in a -48V system
Hi Sir, For a system with -48V and 0V (Ground) power rails, can I use the STEF01 with the following connections?Connect the IC's GND pin to the system -48V rail.Connect the IC's VCC pin to the system 0V rail. Will the chip work correctly and safely ...
Basic Model vs. Electro-thermal Model of TVS Diodes
Hello,I have some questions about ISO7637-2 and ISO16750-2 transient pulse simulations using the basic model and the electro-thermal model of TVS diodes in LTspice.1) In a DC sweep simulation, I observed different IV characteristic curves between the...
STEVAL STWBC86TX programming
Hello, I would like to program a board with the initial configuration of the STEVAL STWBC86TX. To do this, I need two files: PATCH and CONFIG. Where can I download these files to the STSW-WPSTUDIO GUI of the test board we have?
