LED Driver IC for Lighting MB39C604 Low BOM Available for a Wide Range of LED Lighting Applications from 5W to 50W MB39C604 is a PSR-type LED driver IC for LED lighting. Using the information of the primary peak current and the transformer-energyzero time, it is able to deliver a well regulated current to the secondary side without using an opto-coupler in an isolated flyback topology. Using critical conduction mode, it is able to allow the use of a small transformer. features • FIyback topology Switching Regulator • SW Method: PSR (Primary Side Regulation), Switching On-time Control • Application of up to 50W • High Efficiency (>85%) and Low EMI • High Power Factor in Single Conversion by PFC (Power Factor Correction) Function • Both Isolation type and Non-Isolation type can be configured • Universal Input Voltage: 85VAC to 265VAC • PWM Dimming available MB39C604 is used for a wide range of applications, such as general LED lighting (bulb, tube, down light, ceiling light, etc) for residential and commercial property, wireless-controlled lighting by remote controller and sensor using PWM dimming function, and high wattage LED lighting for street and high-bay lights. block diagram and specifications Isolation Type AC Line ITEM LED SPECIFICATIONS SW FET External Junction Temp.
