【文字介紹】

The RT8514 is a high frequency, asynchronous boost converter. 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, the RT8514 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.

The RT8514 is available in the tiny package type TSOT-23-6 package to provide the best solution for PCB space saving and total BOM cost.
