LinkSwitch-XT
Monolithic IC with 700 V Power MOSFET and Thermal Shutdown
- Spec name: Incorporates a 700 V power MOSFET
- Spec name: Simple ON/OFF control scheme
- Spec name: High voltage switched current source
- Spec name: Frequency jittering
- Features:
- 700 V power MOSFET
- Simple ON/OFF control
- High voltage switched current source
- Thermal shutdown circuitry
LinkSwitch-XT incorporates a 700 V power MOSFET, oscillator, simple ON/OFF control scheme, a high voltage switched current source, frequency jittering, cycle-by-cycle current limit and thermal shutdown circuitry onto a monolithic IC. The start-up and operating power are derived directly from the DRAIN pin, eliminating the need for a bias winding and associated circuitry.
LNK419EG
LED Driver with PF>0.9, TRIAC Dimming, and Constant Current Control
- Spec name: 725 V power FET
- Spec name: Continuous-mode PWM controller
- Spec name: High-voltage switched current source
- Features:
- Power factor correction
- Constant-current output
- No electrolytic capacitors
- Primary-side PWM dimming
The LNK419EG dramatically simplifies implementation of LED drivers requiring long lifetime, high efficiency, PF >0.9, and TRIAC dimming capability. 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 LNK419EG device provides accurate constant current control while eliminating the need for an optocoupler and current sensing circuits.
LinkSwitch-PH
Single-Stage Power Factor Correction and Constant-Current Controller
- Spec name: 725 V power FET
- Spec name: Continuous-mode PWM controller
- Spec name: High-voltage switched current source
- Features:
