The following document contains information on Cypress products. FUJITSU SEMICONDUCTOR FACT SHEET 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 x 5.05mm x 1.75mm [Max]) APPLICATIONS LED lighting PWM dimmable LED lighting etc PACKAGE 8-pin plastic SOP-8 (FPT-8P-M02) November 2012 1/2 Copyright(c)2012 FUJITSU SEMICONDUCTOR LIMITED All rights reserved MB39C602 PIN ASSIGNMENTS TOP VIEW Pin No. Pin Name 1 FC 2 ZCD I/O I I FC 1 8 VDD ZCD 2 7 GND 3 CL I CL 3 6 DRN 4 5 VCG 4 5 6 7 8 OTC VCG DRN GND VDD I O - OTC Description Switching frequency setting pin.
