Description  
Notes:  
The LinkSwitch-II dramatically simplifies low power CV/CC  
charger designs by eliminating an optocoupler and secondary  
control circuitry. The device introduces a revolutionary control  
technique to provide very tight output voltage and current  
regulation, compensating for transformer and internal parameter  
tolerances along with input voltage variations.  
1. Minimum continuous power in a typical non-ventilated enclosed adapter  
measured at +50 °C ambient, device, TJ <100 °C.  
2. Maximum practical continuous power in an open frame design with adequate  
heatsinking, measured at 50 °C ambient (see Key Applications Considerations  
section for more information).  
3. Packages: P: DIP-8C, G: SMD-8C, D: SO-8C.  
The device incorporates a 700 V power MOSFET, a novel ON/OFF  
control state machine, a high voltage switched current source for  
self biasing, frequency jittering, cycle-by-cycle current limit and  
hysteretic thermal shutdown circuitry onto a monolithic IC.
