LinkSwitch-TN
Replaces Linear, Resistive / Capacitive Droppers in Home Appliance and Industrial Applications
Typical Buck Converter Application
Description:
- Lowest cost and component count buck converter solution
- 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
- 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
- Enables a 100% SMD designed power supply
Applications:
- Non-isolated buck or buck-boost converter solution for linear/passive dropper replacement
- Major and small home appliances
- Industrial controls
- Utility meters
- Constant current LED lighting
- Timers
