LNK304 LinkSwitch-TN step-down converter
The Power Integrations LNK304 LinkSwitch ™ -TN family of devices is comprised of converter-down-voltage ICs that provide a step-down solution with a low number of components. The LNK304 has been designed to offer a more efficient alternative to linear and passive component solutions.
Applications
The LNK304 LinkSwitch step-down converter is ideal for fixtures and timers, LED drivers and industrial controls.
Characteristics
Fully integrated automatic restart function for short circuits and open loop fault protection
66 kHz operation with precise current limitation
Small tolerance margins and negligible temperature variation
High bypass voltage 700 V
Frequency modulation dramatically reduces EMI (∼10 dB)
Integrated current limit and hysteretic thermal protection
High thermal shutdown temperature (+135 ° C minimum)
Consumes only 50 to 80 mW typically in a self-powered step-down topology with a 115/230 VAC no-load input (opto-feedback)
Consumes only 7 to 12 mW typically in a Flyback topology with external bias to 115/230 VAC no-load input
LinkSwitch-TN is specially designed to replace all non-isolated linear and capacitor (capacitive injector) power supplies in the output current range below 360mA, for the same system cost, while providing performance and energy efficiency much higher. LinkSwitch-TN devices incorporate a 700V power MOSFET transistor, oscillator, simple on / off control mechanism, high voltage switched current source, frequency modulation, cycle-by-cycle current limit and circuit thermal break on a monolithic IC.
Small tolerance margins and negligible temperature variation
System level thermal overload, output short circuit and open loop protection
Support for Step-Down, Step-Up and Flyback topologies
Excellent line and load regulation even with typical configuration
Wide bandwidth guarantees quick start-up without overshoot
Current limited operation rejects line ripple
Integrated current limit and hysteretic thermal protection
