Accurate hysteretic thermal shutdown protection –
automatic recovery improves fi eld reliability
Universal input range allows worldwide operation
Simple ON/OFF control, no loop compensation needed
Eliminates bias winding – simpler, lower cost
transformer
Very low component count – higher reliability and single
side printed circuit board
Auto-restart reduces delivered power by 95% during
short circuit and open loop fault conditions
High bandwidth provides fast turn-on with no overshoot
and excellent transient load response

市場為什么會出現“冰火兩重天”的情況？以ADI為例，短期來看，是由于短期受疫情影響帶來的供需不平衡導致，其后深層次來看是由于技術壁壘。

和大漲的ADI產品不用，此前一路上漲的MLCC和存儲產品價格上漲已經暫緩，市場上的貿易商朋友反饋主要和市場需求疲軟有關。而另一面，以ADI、美信為代表的主動元件卻一度出現漲價也無貨的情況。

從目前獲取的信息來看，封城時間內，企業多采用停工和減少產能的措施。退一步來說，多數國家航線減少或停飛，即使是能夠運輸成本也在增加。
