Typical Application Using R1205N823C PWM Step-Up DC-DC Converter for White LED/PMOLED. The R1205x/R1207N Series are CMOS-based PWM step-up DC/DC converters, which are optimized to drive white LEDs and PMOLED with constant current. There are two types. The A version is optimized for the general use or the drive of PMOLED, and the B/C version is optimized for the serial drive of white LED with constant current
