NP405-00005-1v0-E
High Power Factor LED Driver IC for LED lighting
MB39C602
MB39C602 is a flyback type switching regulator controller IC. The LED current is regulated by controlling
the switching on-time depending on the LED load.
It is most suitable for the general lighting applications, for example stocks of commercial and residential
light bulbs and so on.
■DESCRIPTION
High power factor in Single Conversion
Helps to achieve high efficiency and low EMI by detecting transformer zero current
Frequency setting depend on the FC pin current : 30 kHz to 120 kHz
Control of the current of Primary Winding without the external sense resistor
Built-in under voltage lock out function
Built-in output over voltage protection function
Built-in over temperature protection function
Input voltage range VDD : 9V to 20V
Input voltage range for LED lighting applications : AC110VRMS, AC230VRMS
Package : SOP-8 (3.9mm × 5.05mm × 1.75mm [Max])
■ APPLICATIONS
LED lighting
PWM dimmable LED lighting etc
