MB39C601 for LED Lighting AC/DC Flyback Controller IC Description MB39C601 is a switching regulator controller with the Flyback topology. This product is designed to drive 6W or 15W LED lighting in series, and supports worldwide AC input voltage ranging from 85 to 265 volts. Based on the LED load, the MB39C601 can control the switching on-time (constant on-time mode) or the switch- ing frequency (peak current mode) will achieve a high power factor and high efficiency to save energy. The MB39C601 is suitable for general lighting applications that require few peripheral components and a low price.

MB39C601 for LED LightingAC/DC Flyback Controller IC
DescriptionMB39C601 is a switching regulator controller with the Flyback topology. This product is designed to drive 6W or 15W LED lighting in series, and supports worldwide AC input voltage ranging from 85 to 265 volts.
Based on the LED load, the MB39C601 can control the switching on-time (constant on-time mode) or the switch-ing frequency (peak current mode) will achieve a high power factor and high efficiency to save energy. The MB39C601 is suitable for general lighting applications that require few peripheral components and a low price.
Features• Suitable for LED lighting
• High power factor for the constant on-time mode
• High efficiency at the light load for the peak current mode
• Frequency setting: 30kHz to 130kHz (depending on the FB pin current)
• Input voltage range for LED lighting applications: 100VAC to 230VAC
• Primary current sensing with cascode connection requires no current sense resistor
• Compatible with TRIAC dimmable LED lighting
• Achieves high efficiency and low EMI by detecting transformer zero energy
• Built-in various protection functions: Under Voltage Lock-out (UVLo), Over Load Protection (OLP), Over Voltage Protection (OVP), Over Temperature Protection (OTP)
Package• SOP-8• 3.9mm×5.05mm×1.75mm
(Pin pitch 1.27mm)
