Energy Effi cient, Low Power Off-Line Switcher IC:LinkSwitch-XT incorporates 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 ® Table 1. Notes: 1. Minimum continuous power in a typical nonventilated enclosed adapter measured at 50 °C ambient. 2. Minimum practical continuous power in an open frame design with adequate heat sinking, measured at 50 °C ambient. 3. Packages: P: DIP-8B, G: SMD-8B. Please see Part Ordering Information. 4. See Key Application Considerations section for complete description of assumptions.
