Lowest System Cost with Zero Standby Consumption

• Simple system configuration provides zero consumption standby/

power-down with user controlled wake up

• Very tight IC parameter tolerances improves system manufacturing yield

• Suitable for low-cost clampless designs

• Frequency jittering greatly reduces EMI filter cost

• Extended package creepage improves system field reliability

Advanced Protection/Safety Features

• Hysteretic thermal shutdown protection – automatic recovery reduces field returns

• Universal input range allows worldwide operation

• Auto-restart reduces delivered power by >85 during short-circuit

and open-loop fault conditions

• Simple ON/OFF control, no loop compensation needed

• High bandwidth provides fast turn on with no overshoot

EcoSmart™– Energy Efficient

• Standby/power-down consumption less than 3 mW at

325 VDC input (Note 1)

• Easily meets all global energy efficiency regulations with no added

components

• ON/OFF control provides constant efficiency to very light loads

Applications

• Ultra low consumption isolated or non-isolated standby and auxiliary

supplies
