RT8510 - 43V 4-CH LED Driver

Description

The RT8510 is a high efficiency driver for white LEDs.

It is designed for LCD panels that employ an array of LEDs as the lighting source.

An integrated switch current mode boost controller drives four strings in parallel and supports up to 12 pieces of LED per string.

® RT8510 43V 4-CH LED Driver General Description The RT8510 is a high efficiency driver for white LEDs. It is designed for LCD panels that employ an array of LEDs as the lighting source. An integrated switch current mode boost controller drives four strings in parallel and supports up to 12 pieces of LED per string. The internal current sinks support a maximum of ±2% current mismatching for excellent brightness uniformity in each string of LED. To provide enough headroom for current sink operation the boost controller monitors the minimum voltage of feedback pins and regulates an optimized output voltage for power efficiency. The RT8510 has a wide input voltage range from 4.2V to 24V and provide an adjustable 10mA to 40mA LED current.
