The ISL97671A 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 ISL97671A can drive six channels of
LEDs from an input of 4.5V~26.5V to an output of up to 45V. It
can also operate from an input as low as 3V to an output of up
to 26.5V in bootstrap configuration (see Figure 38).
The ISL97671A features optional channel phase shift control
to minimize the input: output ripple characteristics and load
transients to improve efficiency and eliminate audible noise.
The device can also be configured in Direct PWM Dimming
with minimum dimming duty cycle of 0.007 at 200Hz.
The ISL97671A headroom control circuit 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 ISL97671A is offered in compact and thermally efficient
20 Ld QFN 4mmx3mm package.
