LinkSwitch-TN Family
Lowest Component Count, Energy Efficient
Off-Line Switcher IC
Figure 1. Typical Buck Converter Application (See Application
Examples Section for Other Circuit Configurations).
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
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 Blue Angel, Energy Star, and EU requirements
Applications
Appliances and timers
LED drivers and industrial controls
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 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.
