LinkSwitch™-PH
Dramatically simplifies implementation of LED drivers
LinkSwitch™-PH from Power Integrations dramatically simplifies implementation of LED drivers requiring power factors greater than 0.9, TRIAC dimming, and high efficiency. This highly integrated controller introduces a new control technique that provides very high power factor, accurate output current control, and eliminates the passive circuitry required for power factor correction, optocoupler and secondary current control circuitry.
Each device 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 into a monolithic IC.
