LinkSwitch-TN, Power Integrations

The LinkSwitch-TN family of very low power AC-DC, Non-Isolated passive power supply replacements.

700 V Internal MOSFET Rating
Self-Powered
ON/OFF Control
Hysteretic Thermal Shutdown
Power Limiting
Frequency Jitter Reduces EMI
EcoSmart Low Standby/No-load Power Consumption

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. LinkSwitch-TN devices integrate a 700 V power MOSFET, oscillator, simple On/Off control scheme, a high-voltage switched current source, frequency jittering, cycle-by-cycle current limit and thermal shutdown circuitry onto a monolithic IC.

Tight tolerances and negligible temperature variation
System level thermal overload, output short-circuit and open loop protection
Supports buck, buck-boost and flyback topologies
Excellent line and load regulation even with typical configuration
High bandwidth provides fast turn-on with no overshoot
Current limit operation rejects line ripple
Built-in current limit and hysteretic thermal protection
