MIP551/MIP552 is the best device for LED-lighting.
LED-lighting using MIP551/MIP552 has small size & high efficiency by simple design in worldwide input voltage(80 VAC to 280 VAC), and has dimmer control function by external signal.
Features
- Worldwide input voltage, 80 VAC to 280 VAC
- Typical LED peak current
MIP551 : 0.5 A
MIP552 : 1.0 A
* Peak current can be adjusted in two-stage corresponding to the input voltage. - Dimmer control function : EX-pin voltage range, 0 V to 3 V
- Function to set input voltage that can be driven
:L-pin voltage range - Over temperature protection for IPD (Auto-restart)
Applications
LED-lighting
HB-LED drive circuit
