此芯片是新推出的吧,有点不可靠吧

Thank you for your reply! I have got the IR1150 sample last month. It is mainly for 220VAC input, boost application. However, My application is 380VAC input (3 phase) buck topology (require 500VDC output).

It is said about $200. An IR office in ShenZhen can provide the demo board.
