Overview

Preliminary RT4526 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...
