LNK362DN

Микросхема LNK362DN (LNK362)

LNK362DN - Energy Efficient, Low Power Off-Line Switcher IC, SOP-7

 

 

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 efficiency
• 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 field 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 Efficient

• Easily meets all global energy efficiency 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

 

Применение

• Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio players, and shavers
• Supplies for appliances, industrial systems, and metering
