LinkSwitch-LP  
Energy Efcient Off-Line Switcher IC for  
Linear Transformer Replacement  
Product Highlights  
+
DC  
Output  
Lowest System Cost and Advanced Safety Features  
AC  
IN  
Lowest component count switcher  
Very tight parameter tolerances using proprietary IC  
trimming technology and transformer construction  
techniques enable Clampless™designs – decreases  
component count/system cost and increases efciency  
Meets industry standard requirements for thermal overload  
protection – eliminates the thermal fuse used with linear  
transformers or additional components in RCC designs  
Frequency jittering greatly reduces EMI – enables low cost  
input lter conguration

Meets HV creepage requirements between DRAIN and all  
other pins, both on the PCB and at the package  
Proprietary E-Shield™ transformer eliminates Y-capacitor  
Rated Output Power = VR IR  
Superior Performance over Linear and RCC  
Hysteretic thermal shutdown protection – automatic  
recovery improves eld reliability  
Universal input range allows worldwide operation  
Auto-restart reduces delivered power by >85% during  
short circuit and open loop fault conditions

Notes:  
1. Output power may be limited by specic application parameters  
including core size and Clampless operation (see Key Application  
Considerations).  
2. Minimum continuous power in a typical non-ventilated enclosed  
adapter measured at 50 °C ambient.  
3. Minimum practical continuous power in an open frame design with  
adequate heat sinking, measured at 50 °C ambient.  
4. Packages: P: DIP-8B, G: SMD-8B, D: SO-8C. For lead-free  
package options, see Part Ordering Information.
