The RT9293 is a high frequency, asynchronous boost
converter. The internal MOSFET can support up to 10
White LEDs for backlighting andOLEDpower application,
and the internal soft start function can reduce the inrush
current. The device operates with 1-MHz fixed switching
frequency to allow ***all external components and to
simplify possible EMI problems. For the protection, the
RT9293A provides 50VOVP and the RT9293B provides
50V/20V OVP to allow inexpensive and ***all-output
capacitors with lower voltage ratings. The LEDcurrent is
initially set with the external sense resistor RSET. The
RT9293 is ***ailable in the tiny package type TSOT-23-6
andWDFN-8L 2x2 packages to provide the best solution
for PCB space s***ing and total BOM cost.
