The RT4539A is a high efficiency driver for white LEDs. It is suitable for single/two cell battery input to drive LED light bars which contains six strings in parallel. The internal current sinks support a maximum of ±2% current mismatching for excellent brightness uniformity in each string of LEDs. To provide enough headroom for current sink operation, the Boost converter monitors the minimum voltage of the feedback pins and regulates an optimized output voltage for power efficiency. The RT453.
