Power Integrations LNK406E
This pin is the power FET drain connection. It also provides internal operating current for both start-up and steady-state operation.FEATURES
● Auto-restart for short-circuit protection● Open circuit fault detection mode
● Automatic thermal shutdown restart with hysteresis
● Meets high voltage creepage requirement between DRAIN and all other signal pins both on PCB and at package Green Package
● Halogen free and ROHS compliant package
APPLICATIONS
● Off-line LED driverDESCRIPTION
The LinkSwitch™-PH dramatically simplifies implementation of LED drivers requiring long lifetime, high efficiency, PF >0.9, and TRIAC dimming capability (LNK403-410). 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.
