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.y Worldwide input voltage, 80 VAC to 280 VAC

y Typical LED peak current

MIP551: 0.5A

MIP552: 1.0Ａ

*Peak current can be adjusted in two-stage

corresponding to the input voltage.

y Dimmer control function : EX-pin voltage range, 0 V to 3 V

y Function to set input voltage that can be driven :L-pin voltage range y Over temperature protection for IPD (Auto-restart)LED-lighting

HB-LED drive circuit

output power （Ta=25°C)

RON VDSS Item 1）The maximum output power is different depending on parts and ambient conditions, so the following value is a reference value.

2）When the input power is more than 25W, it is necessary to connect PFC circuit in input side.

3) It is possible to drive without the smoothing aluminum electrolytic capacitor when the input voltage detecting function is used. 4) When the line voltage detecting function or LED dimmer control function is not used, the circuit can be simplified. DRAIN
