Small Package, High Performance, Asynchronous BoostLED Driver
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 small-output capacitors ,with lower voltage ratings. The LED current is initially set with the external ,sense resistor RSET. The RT4526 is available in the tiny TSOT-23-6 package to ,provide the best solution for PCB space saving and total BOM cost.
