Description

The LinkSwitch-PH dramatically simplifies implementation of LED drivers requiring PF > 0.9, TRIAC dimming and high efficiency. The highly integrated controller eliminates passive circuitry required for power factor correction, optocoupler and secondary current control circuitry. LinkSwitch-PH introduces a new control technique that provides very high power factor and accurate output current control. LinkSwitch-PH incorporates a 725 V power MOSFET, a continuous-mode PWM controller, a high voltage switched current source for self biasing, frequency jittering, cycle-by-cycle current limit and hysteretic thermal shutdown circuitry, all in a monolithic IC.
