Description

[ FERYSTER Inductive Components Manufacturer ]

Description

LinkSwitch-TN is specifically designed 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

Product Category: AC DC Converters, Offline Switchers

• Cost Effective Linear/Cap Dropper Replacement
• Fully integrated auto-restart for short-circuit and open loop fault protection – saves external component costs
• 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)
• Supports buck, buck-boost and flyback topologies
• Entirely manufacturable in SMD

Application Scenarios

• Appliances and timers
• LED drivers and industrial controls
