LinkSwitch-PH Series AC / DC LED Driver ICs:
3 Products FoundLinkSwitch-PH Series AC / DC LED Driver ICs
The LinkSwitch-PH dramatically simplifies implementation of LED drivers requiring PF> 0.9, TRIAC dimming and high efficiency. 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.
- Single stage power factor correction and accurate constant current (CC) output
- Flicker-free phase-controlled TRIAC dimming
- Eliminates optocoupler and all secondary current control circuitry
- Simple primary-side PWM dimming interface
- Compensates for transformer inductance tolerances
- Frequency jittering greatly reduces EMI filter size and costs
- Low standby power remote ON/OFF feature (<50 mW="" at="" 230="" VAC)<=""/>
- Auto-restart for short circuit protection
- Automatic thermal shutdown restart with hysteresis
- Applications: Commercial & Industrial lighting, Indoor lighting, Outdoor lighting.
