L7987L SPICE Model
Hi, I am looking for SPICE model for L7987L IC. Please share if anyone has it.
Resolved! L6924D MOS Max Current
What's the max current of the mosfet in the L6924D?We want to use AC adaptor to charge the battery and supply the system loading at the same time. So, we want to know the max current of power mosfet.Thank you.
Resolved! STSW-DABBIDIR , where is the code.
Imagine my susprise when i discovered ST actually offers a DAB "software" for their 25KW evaluation board using stm32G474RE. And i go to ST's website.And the only downloadables are binary files and a lazy one page .pdf Am i missign something here? wh...
Transformer saturation current calculation when using STCH03
I believe the VCX comparator is designed to clamp the maximum primary current, but there is no equation in Figure 7 of the datasheet to describe the relationship between IFF, RFF, and line voltage. Without an equation for IFF, it is difficult to size...
Resolved! Execution Halt in STEVAL-7BIDIRCB eDesignSuite Reference Code at DPC_FSM_INIT_Func()
Dear ST Technical Support Team,We are encountering a blocking issue when running the eDesignSuite-generated reference code for STEVAL-7BIDIRCB. The specific workflow is:Power up the STM32G474 MCU firstApply 220V/50Hz AC inputProblem Description:The p...
Resolved! Seeking Assistance with 7KW PFC Circuit Based on STEVAL-7BIDIRCB Design
Dear ST Community Members,I have built a 7KW three-phase interleaved totem pole PFC circuit (based on the schematic of STEVAL-7BIDIRCB, retaining only the PFC section). The firmware was generated using ST eDesignSuite's "FW download" tool. Before pow...
