TEA1995T 是同步整流的控制器不含GaN HEMT

TEA2016AAT 是PFC加LLC的控制芯片,不含GaN HEMT,單價7.25RMB,光光控制器就超過1USD,加上HEMT不得了


TEA1995T 是同步整流的控制器,也不含GaN HEMT,和我們不是同類的產品


HL9550 確實是整合型的反激控制器 和我們很類似 但是它是QFN5X6包裝,散熱pad 3.45mmx3.2mm

客戶反映用在65W熱的問題很嚴重(客戶認為不可能在110V的國家使用),而我們用QFN8x8

散熱面積3mmx6.4mm幾乎是兩倍,所以散熱好很多。而且我們單價差不多


ONSEMI NCP1342是控制器不含GaN HEMT,如果單價2.36RMB(0.33USD), 加上HEMT開關都會超過1.1USD

而且還要加level shifter的驅動電路

BALZERS BA 510 rare release

Good day, how are you? I am working with a client who is looking to release a BALZERS/BA 510 this quarter. I understand you were once intereted in similar model so I want to check if this is something you would consider buying. They used this for a project that’s concluded and no longer require this in-house, and are motivated to make space at their facility. You may review the asset in the link below. If you need any further information to review, please let me know.
