RT9292 Small Package, High Performance, Asyn-Boost Converter for 6 White LEDs General Description The RT9292 is a high frequency and high efficiency asynchronous boost converter for WLED driving application. It integrates a 28V MOSFET to support up to 6 White LEDs for panel backlighting and OLED power applications. Besides, an internal soft start function is integrated to reduce the inrush current. Moreover, the device operates with 1MHz fixed switching frequency for the use of small external components and better EMI performance. For lower voltage application, the IC provides a 26V over voltage protection function for using the lowcost and small output capacitors.
