Small Package, High Performance, Asynchronous Boost
LED Driver
General Description
The RT4526 is a high frequency, asynchronous boost
converter. This converter can support 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 RT4526 provides 30V
OVP to allow inexpensive and small-output capacitors with
lower voltage rating. The LED current is initially set with
the external sense resistor RSET. The RT4526 is available
in the tiny package type TSOT-23-6 package to provide
the best solution for PCB space saving and total BOM
cost.
