RT8555 Datasheet | Richtek

® 36V High Efficiency Boost Converter with I2C Controlled 6-CH LED Driver General Description The RT8555 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 and up to 10 WLEDs per string. 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 controller monitors the minimum voltage of the feedback pins and regulates an optimized output voltage for power efficiency. The RT8555 has a wide input voltage operating range from 2.7V to 24V and...
