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 simplied 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 mAoutput 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 lter cost
High thermal shutdown temperature (+135 °C minimum)
Much Higher Performance over Discrete Buck and
Passive Solutions
Supports buck, buck-boost and yback topologies
System level thermal overload, output short-circuit and
open control loop protection
Excellent line and load regulation even with typical
conguration
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 efciency than passive solutions
Higher power factor than capacitor-fed solutions
Entirely manufacturable in SMD
EcoSmart
– Extremely Energy Efcient
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 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 specically designed to replace all linear and
capacitor-fed (cap dropper) non-isolated power supplies in the
Table 1.
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. 4. Packages: P: DIP-8B, G: SMD-8B.

under 360 mA output current range at equal system cost while
offering much higher performance and energy efciency.
LinkSwitch-TN
devices integrate a 700 V power MOSFET,
oscillator,simpleOn/Offcontrolscheme,ahighvoltageswitched
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 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.
