توضیحات
آي سي LNK364PN يک مبدل AC به DC با توان کم 9 وات مي باشد.
آي سي LNK364PN از خانواده آي سي هاي سوئيچينگ LinkSwitch-XT با راندمان بالا و توان 6 وات مي باشد که در شارژها، آداپتورها، منابع تغذيه سوئيچينگ صنعتي و ... کاربرد دارد. اين آي سي امکان ساخت تغذيه هاي سوئيچينگ (Off-line (AC to DC با کمترين ميزان استفاده از قطعات خارجي فراهم مي کند. از ويژگي هاي اين آي سي، مدار يکپارچه ريستارت اتوماتيک به هنگام اتصال کوتاه و يا شرايط خطا براي محافظت از آي سي، محافظت حرارتي به هنگام افزايش دما و... مي باشد. حداکثر ولتاژ درين ماسفت آي سي LNK364 تا 700 ولت با پيک جريان 400mA است همچنين فرکانس سوئيچ اين آي سي 132KHz با ديوتي سايکل 60% مي باشد.
Description
LNK362-364
LinkSwitch-XT Family
Energy Effi cient, Low Power
Off-Line Switcher IC
Optimized for Lowest System Cost
• Proprietary IC trimming and transformer construction
techniques enable Clampless™ designs with LNK362
for lower system cost, component count and higher
effi ciency
• Fully integrated auto-restart for short circuit and
open loop protection
• Self-biased supply – saves transformer auxiliary winding
and associated bias supply components
• Frequency jittering greatly reduces EMI
• Meets HV creepage requirements between DRAIN and
all other pins both on the PCB and at the package
• Lowest component count switcher solution
Features Superior to Linear/RCC
• 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
EcoSmart®
– Extremely Energy-Effi cient
• Easily meets all global energy effi ciency regulations with
no added components
• No-load consumption <300 mW without bias winding at
265 VAC input (<50 mW with bias winding)
• ON/OFF control provides constant effi ciency to very
light loads – ideal for mandatory CEC regulations
Applications
• Chargers/adapters for cell/cordless phones, PDAs, digital
cameras, MP3/portable audio players, and shavers
• Supplies for appliances, industrial systems, and metering
