The RT4501/A is a high-efficiency LED driver for backlight
applications. An asynchronous boost converter with an
internal Schottky diode and a current source driver are
designed to support 6LED/channel with wide input voltage
range from 2.5V to 5.5V.
An I2C interface can provide easy backlight control in fast
and high speed mode. The RT4501 supports linear
mappings with 256 steps to setup the brightness of
backlight LEDs. It also supports PWM dimming to adjust
the brightness.
For brightness dimming, the RT4501A supports 128 steps
pulse dimming which determines the LED current, and
RT4501 support 256 steps PWM dimming which
determines the LED current.
