General Description
The RT8560 is a 60V 4-channel LED driver capable of
delivering 30mA to each channel with 15 LEDs (3.6V per
diode) total 60 LEDs with one driver. The RT8560 is a
current mode boost converter opearated at 1MHz switching
frequency, wide VIN range covers from 7V to 40V and the
on-chip current switch is rated at 1.5A.
The PWM output voltage loop selects and regulates the
LED pin with the highest voltage string to 0.9V allowing
voltage mismatches between LED strings. The RT8560
automatically detects and disconnects any unconnected
and/or broken strings during operation from PWM loop to
prevent VOUT from over voltage.
The 3% matched LED currents on all channels are simply
programmed with a resistor or a current sink. Both analog
dimming and digitally controlled PWM dimming are
supported by RT8560. Analog dimming is linearly
controlled by an external voltage. With an on-chip output
clampping amplifier and a 200k
Ω resistor, PWM dimming
signal is easily low-pass filtered to an analog dimming
signal with one external capacitor for noise-free PWM
dimming. A very high contrast ratio true digital PWM
dimming can be achieved by driving EN pin to PWM
shutdown the chip or by driving ACTL pin.
Other protecting features include programmable PWM
output over voltage protection, LED curren limit, PWM
switch current limit and thermal shutdown. The RT8560
is packaged with a tiny footprint package of WQFN-20L
4x4 packages.
