LNK302/304-306

LinkSwitch-TN Family

Lowest Component Count, Energy-Effi cient Off-Line Switcher IC

 

Product Highlights

Cost Effective Linear/Cap Dropper Replacement

• Lowest cost and component count buck converter solution

• Fully integrated auto-restart for short-circuit and open loop fault protection – saves external component costs

• LNK302 uses a simplifi ed controller without auto-restart for very low system cost

• 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 fi lter cost

• High thermal shutdown temperature (+135 °C minimum)

 

Much Higher Performance over Discrete Buck and Passive Solutions

• Supports buck, buck-boost and fl yback topologies

• System level thermal overload, output short-circuit and open control loop protection

• Excellent line and load regulation even with typical confi guration

• 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 effi ciency than passive solutions

• Higher power factor than capacitor-fed solutions

• Entirely manufacturable in SMD

 

EcoSmart® – Extremely Energy Effi cient

• Consumes typically only 50/80 mW in self-powered buck topology at 115/230 VAC input with no load (opto feedback)

• Consumes typically only 7/12 mW in fl yback topology with external bias at 115/230 VAC input with no load

• Meets California Energy Commission (CEC), Energy Star, and EU requirements

 

Applications

• Appliances and timers

• LED drivers and industrial controls

 

Description

LinkSwitch-TN is specifi cally 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 effi ciency. ® 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. The startup and operating power are derived directly from the voltage on the DRAIN pin, eliminating the need for a bias supply and associated circuitry in buck or fl yback converters. The fully integrated auto-restart circuit in the LNK304-306 safely limits output power during fault conditions such as short-circuit or open loop, reducing component count and system-level load protection cost. A local supply provided by the IC allows use of a non-safety graded optocoupler acting as a level shifter to further enhance line and load regulation performance in buck and buck-boost converters, if required.

1. All voltages referenced to SOURCE, TA = 25 °C.

2. The higher peak DRAIN current is allowed if the DRAIN to SOURCE voltage does not exceed 400 V.

3. Normally limited by internal circuitry.

4. 1/16 in. from case for 5 seconds.

5. Maximum ratings specifi ed may be applied, one at a time, without causing permanent damage to the product. Exposure to Absolute Maximum Rating conditions for extended periods of time may affect product reliability.
