LinkSwitch-TN Family

Lowest Component Count, Energy Efficient

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

• 66 kHz operation with accurate current limit - allows low

cost off-the-shelf 1 mH inductor for up to 120 mA output

current

Wide Range

LinkSwitch-TN

HV DC Input

Output

• Tight tolerances and negligible temperature variation

• High breakdown voltage of 700 V provides excellent

input surge withstand

PI-3492-111903

• Frequency jittering dramatically reduces EMI (~10 dB) -

minimizes EMI filter cost

Figure 1. Typical Buck Converter Application (See Application

Examples Section for Other Circuit Configurations).

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

OUTPUT CURRENT TABLE⁽¹⁾

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

230 VAC ±15%

• Excellent line and load regulation even with typical

configuration

LNK306P or G 225 mA 360 mA 225 mA 360 mA

• 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

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. Please see

ordering information.

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

LinkSwitch-TN devices integrate a 700 V power MOSFET,

oscillator,simpleOn/Offcontrolscheme,ahighvoltageswitched

currentsource, frequencyjittering, cycle-by-cyclecurrentlimit

and thermal shutdown circuitry onto a monolithic IC. The start-

upandoperatingpowerarederiveddirectlyfromthevoltageon

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

componentcountandsystem-levelloadprotectioncost. Alocal

supply provided by the IC allows use of a non-safety graded

optocoupler acting as a level shifter to further enhance line and

loadregulationperformanceinbuckandbuck-boostconverters,

if required.

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.
