The RT9293BGJ6 is a high performance Asynchronies Boost for 10W LED driver. The internal MOSFET can support up to 10 white LEDs for backlighting and OLED power application and the internal soft start function can reduce the inrush current. The device operates with 1MHz fixed switching frequency to allow small external components and to simplify possible EMI problems. For the protection, it provides 50/20V OVP to allow inexpensive and small-output capacitors with lower voltage ratings. The LED current is initially set with the external sense resistor RSET.
