I am using the TPS92641EVM to conduct a LED shunt dimming test. The test conditions and setup are as follows: (1)Input Voltage: 43.5V,LED Load: 32V / 1A (2)Connection: 10-meter cable is connected between the LED and the TPS92641EVM. (3)SDIM Input: 100:1 PWM signal ( f = 2 kHz ) (4)Shunt MOSFET: FKD4014 driven by the SDRV pin Currently, I am unable to successfully achieve a target current pulse width of 5us at 200 mA. Could you please help check my setup and advise on what modifications or adjustments are required to resolve this issue? Thank you!TPS92641EVM工业自动化https://e2echina.ti.com/support/tools/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1079084/pspice-for-ti-failed-to-place-symbol-instance-for-model-s-because-library-analog-does-not-exist/3884967Fri, 12 Jun 2026 01:37:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:a8a138c6-e6f3-4808-adb5-bd071f36e02dFRANK1感谢您对TI产品的关注！ 关于你的咨询，我们正在确认您的问题，感谢您的耐心等待。https://e2echina.ti.com/support/tools/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1079084/pspice-for-ti-failed-to-place-symbol-instance-for-model-s-because-library-analog-does-not-existFri, 12 Jun 2026 01:35:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:26d14b13-5109-484b-a653-37a8d7d7d0aedu jiangfengPart Number: PSPICE-FOR-TI 您好，我在添加基本元器件的时候提示库不存在，请问如何解决该问题或者如何重新添加库PSPICE-FOR-TIhttps://e2echina.ti.com/support/tools/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1078323/tina-ti_simp_chinese-lmr14050-tina/3883061Wed, 10 Jun 2026 06:43:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:66d06b5f-2671-463a-b5da-9b2b3a29f39fVivian Gao参考下方链接的回复。 LMR14050: Cannot import model on Tina-Ti v9 - Simulation, hardware & system design tools forum - Simulation, hardware & system design tools - TI E2E support forumshttps://e2echina.ti.com/support/tools/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1078323/tina-ti_simp_chinese-lmr14050-tina/3882129Tue, 09 Jun 2026 07:48:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:02d4f007-dd53-4fb2-b772-cf70967e086cVivian Gao感谢您对TI产品的关注。 我们正在核实您的问题，请等待我们的答复。https://e2echina.ti.com/support/tools/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1078323/tina-ti_simp_chinese-lmr14050-tinaTue, 09 Jun 2026 07:39:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:09ccc721-f8e6-4c0d-ade7-0a6ec9ba0e4eJerry MaPart Number: TINA-TI 你好，我在官网下载了未加密的模型 https://www.ti.com.cn/cn/lit/zip/snvm923 ，想要在TINA进行仿真，但导入时报错“在定义之前未定义参数或可用函数”，截图如下： 请问我该如何操作解决上述问题，谢谢！ 我的TINA版本如下：TINA-TI_SIMP_CHINESELMR14050TINA-TIhttps://e2echina.ti.com/support/tools/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1078315/dlp4710evm-lc-i-connected-the-power-then-connected-the-usb-d57-is-constantly-on-after-i-pressed-w21-d57---d56-flashes---d57-but-the-projector-still-does-not-turn-on-tTue, 09 Jun 2026 03:28:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:f6eda72d-6584-4ae6-9b77-ffd21e44d955shuang yangPart Number: DLP4710EVM-LC EVM Status: Connected, Powered Off Using a multimeter to measure, when SW21 is pressed, the 1.8V and 1.1V voltages reach a reasonable range, but they immediately drop to 0.联网外设和打印机DLP4710EVM-LChttps://e2echina.ti.com/support/tools/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1078138/pspice-for-ti-pspice-reached-device-access-limit/3882105Mon, 08 Jun 2026 23:47:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:441d9481-cfec-40a1-9a86-37d189ee1b04LydiaHi, PSpice support is now directly managed by Cadence.
