Description

The LNK562GN is an AC DC converter, Offline Switcher electronic component model designed by FERYSTER Inductive Components Manufacturer. The LinkSwitch-TN is engineered to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360 mA output current range at equal system cost while offering much higher performance and energy efficiency.

Specifications and features

• Cost-effective linear/cap dropper replacement
• Fully integrated auto-restart for short-circuit and open loop fault protection that saves external component costs
• 66 kHz operation with accurate current limit that allows a 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)
• Supports buck, buck-boost, and flyback topologies
• System level thermal overload, output short-circuit and open control loop protection
• Excellent line and load regulation even with typical configuration
• 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 efficiency than passive solutions
• Higher power factor than capacitor-fed solutions
• Entirely manufacturable in SMD
• Consumes typically only 50/80 mW in self-powered buck topology at 115/230 VAC input with no load (opto feedback) and consumes typically only 7/12 mW in flyback topology with external bias at 115/230 VAC input with no load to meet California Energy Commission (CEC), Energy Star, and EU requirements.

Application Scenarios

The LNK562GN is suitable for appliances and timers, LED drivers and industrial controls.

Comparison

• The LNK562GN offers higher performance and energy efficiency than linear and capacitor-fed non-isolated power supplies of under 360 mA output current range.
• It offers cost-effective linear/cap dropper replacement and minimizes EMI filter cost.
• The device supports buck, buck-boost, and flyback topologies, and provides much higher power factor and thermal overload protection.

• The LNK562GN is not suitable for power supplies required to deliver over 360 mA output current.
