Power Management ICs Forum Discussions

Hello, I'm using in a project two 2EDB8259F to drive a H-bridge . They are supplied with 5V on input logic side and 12V on output side, the UVLO is 8V in this product code. For some test reason I have to drive INA and INB with two PWM signals, but one is with 3.3V logic levels, the other is with 5V logic levels. In this conditions I have no output in the pins OUTA and OUTB. So, my question is simple, the chip is locked because the logic levels are with different voltages? I don't see any other reason, the load is disconnected at the moment, so OUTA/B and GNDA/B pins are floating. Thanks Show Less

Hello Team ,

We were trying to simulate TLS820F0EL V50 PSpice model in LT Spice XVII but its .lib file is encrypted because of that we were not able to simulate it . So team please let us know how to simulate it in LT Spice XVII .

Hello!
Sorry that I decided to return to this topic again, but I would still like to know how to use flyback converter chips (for example ICE5QSAG) in a switching power supply with a power of about 100 W. When simulating a circuit in SMPS designer tool simulated value of power dissipation of IC is slightly higher than rated value. Are there ways to solve this problem? For example, use a copper area under the IC and connect it to the body with a heat-conducting gasket, or are there any circuit solutions?

does IR3883 need test gain margin and phase margin?

Hi All, I'm using USb 005 programmer which is fixed onto an ICT test fixture to program PMIC device from Infineon, I program the MIC files using the MIC programmer option in the IR PowIRCenter software. But I couldn't find the software is creating any log file for the programming action that is done. As the IR PowIRCenter software doesn't support command line commands I use AutoIT script to automate the mouse clicks and coordinates to open the IR PowIRCenter software and load the .MIC files. Is there any way any log file can be created in the IR PowIRCenter software so that my ICT tester can fetch the log file to acknowledge the successful programming and verification. Also can I use the gang programmer software instead of IR PowIRCenter software and use USB005 programmer to program the PMIC. Hope the gang programmer can generate the log files. Show Less
