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.
