Description  
The LinkSwitch-PH dramatically simplifies implementation of LED  
drivers requiring long lifetime, high efficiency, PF >0.9, and TRIAC  
dimming capability (LNK403-409). The single-stage combined  
power factor and constant-current controller eliminates a switching  
stage and the electrolytic bulk capacitor. The advanced primary-  
side control used by the LinkSwitch-PH device provides accurate  
constant current control while eliminating the need for an  
optocoupler and current sensing circuits.  
LinkSwitch-PH incorporates a 725 V power FET, a continuous-  
mode PWM controller, a high voltage switched current source for  
self biasing, frequency jittering, protection circuitry including  
cycle-by-cycle current limit and hysteretic thermal shutdown.
