® RT4526 Small Package, High Performance, Asynchronous Boost LED Driver General Description Features 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. The RT4526 is available in the tiny TSOT-23-6 package to provide the best solution for PCB space saving and total BOM cost.           VIN Operating Range : 2.5V to 5.5V Internal Power N-MOSFET Switch Wide Range for PWM Dimming (100Hz to200kHz) Minimize the External Component Counts Internal Soft-Start Internal Compensation Under-Voltage Protection Over-Voltage Protection Over-Temperature Protection RoHS Compliant and Halogen Free Applications   Ordering Information  RT4526  Package Type J6 : TSOT-23-6 Cellular Phones Digital Cameras PDAs and Smart Phones and MP3 and OLED.
