LNK304GN smd-7

Микросхема LNK304GN

LNK304GN - Lowest Component Count, Energy-Effi cient Off-Line Switcher IC, SOP-7

 

Cost Effective Linear/Cap Dropper Replacement

• Lowest cost and component count buck converter solution
• Fully integrated auto-restart for short-circuit and open loop fault protection – saves external component costs
• LNK302 uses a simplifi ed controller without auto-restart for very low system cost
• 66 kHz operation with accurate current limit – allows low cost off-the-shelf 1 mH inductor for up to 120 mA output current
• Tight tolerances and negligible temperature variation
• High breakdown voltage of 700 V provides excellent input surge withstand
• Frequency jittering dramatically reduces EMI (~10 dB) – minimizes EMI filter cost
• High thermal shutdown temperature (+135 °C minimum)

 

Much Higher Performance over Discrete Buck and Passive Solutions

• Supports buck, buck-boost and fl yback topologies
• System level thermal overload, output short-circuit and open control loop protection Excellent line and load regulation even with typical confi guration
• High bandwidth provides fast turn-on with no overshoot
• Current limit operation rejects line ripple
• Universal input voltage range (85 VAC to 265 VAC)
• Built-in current limit and hysteretic thermal protection
• Higher effi ciency than passive solutions
• Higher power factor than capacitor-fed solutions
• Entirely manufacturable in SMD
