ISL97673IRZ規(guī)格書詳情
The ISL97673 is a 6-Channel 45V dual dimming capable
LED driver that can be used with either SMBus/I2C or
PWM signal for dimming control. The ISL97673 drives 6
channels of LED to support 78 LEDs from 4.5V to 26V or
48 LEDs from a boost supply of 2.7V to 26V and a
separate 5V bias on the ISL97673 VIN pin
The ISL97673 compensates for non-uniformity of the
forward voltage drops in the LED strings with its 6 voltage
controlled-current source channels. Its headroom control
monitors the highest LED forward voltage string for output
regulation, to minimize the voltage headroom and power
loss in a typical multi-string operation.
The ISL97673 features optional channel phase shift
control to minimize the input, output ripple
characteristics and load transients as well as spreading
the light output to help reduce the video and audio
interference from the backlight driver operation. The
phase shift can be programmed with equal phase angle
or adjustable in 7-bit resolution.
The ISL97673 has a full range of dimming capabilities
that include SMBus/I2C controlled PWM dimming or DC
dimming. Another key feature of the ISL97673 is that it
allows very linear PWM dimming from 0.4 to 100 of
up to 30kHz. Current matching of 0.4 to 100
dimming achieves ±1 tolerance from 100Hz to 5kHz
dimming and ±3 tolerance from 5kHz to 30kHz
dimming.
