Product Summary

The RT9285BGJ6 is a high frequency asynchronous boost converter with internal diode, which can support 2 to 5 White LEDs for back lighting and OLED power supply. The Internal soft start function can reduce the inrush current. The RT9285BGJ6 operates with 1MHz fixed switching frequency to allowsmall external components and to simplify possible EMI problems. The applications of the RT9285BGJ6 include Cellular Phones, Digital Cameras, PDAs and Smart Phones, Porbable Instruments, MP3 Player, OLEDPower.
