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 simplified 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 filter cost
High thermal shutdown temperature (+135
°C
minimum)
Much Higher Performance Over Discrete Buck and
Passive Solutions
Supports buck, buck-boost and flyback topologies
System level thermal overload, output short-circuit and open
control loop protection
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
Entirely manufacturable in SMD
EcoSmart
– Extremely Energy Efficient
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 flyback 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

Notes:
1. Typical output current in a non-isolated buck converter. Output power capability
depends on respective output voltage. See Key Applications Considerations
Section for complete description of assumptions, including fully discontinuous
conduction mode (DCM) operation.
2. Mostly discontinuous conduction mode.
3. Continuous conduction mode.

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.
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 start-up
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 flyback 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.
