•
•
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 efficiency  
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 filter configuration

Table 1. Notes: 1. Output power may be limited by specific 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,
