Powerint LNK605DG 3.7W LED驱动设计方
3.7 W LED Driver Using LNK605DG:90–265 VAC Input; 10.5 V, 350 mA Output DER206设计优势:
Summary and Features
Accurate primary-side constant voltage/constant current (CV/CC) controller eliminates secondary side control and optocoupler
±5% output voltage and ±10% output current accuracy including line, load, temperature and component tolerance
No current-sense resistors for maximized efficiency
Low part-count solution for lower cost
Over-temperature protection–tight tolerance (±5%) with hysteretic recovery for safe PCB temperatures under all conditions
Auto-restart output short circuit and open-loop protection
EcoSmart – Easily meets all existing and proposed international energy efficiency standards–China (CECP) / CEC / EPA / European Commission
ON/OFF control provides constant efficiency to very light loads
No-load consumption <200 mW at 265 VAC
