The RT4526 is a high frequency, asynchronous Boost
converter. The internal MOSFET can support up to 10 white
LEDs for backlighting and OLED power applications, 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, the
RT4526 provides 37V OVP to allow inexpensive and smalloutput
capacitors with lower voltage ratings. The LED
current is initially set with the external sense resistor RSET.资料下载
