ISL97671AIRZ-TK actual photo Pinout
The ISL97671AIRZ-TK 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 ISL97671AIRZ-TK 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. The ISL97671AIRZ-TK 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 for Direct PWM Dimming with a minimum dimming duty cycle of 0.007% at 200Hz. The ISL97671AIRZ-TK 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 ISL97671AIRZ-TK is offered in a compact and thermally efficient 20 Ld QFN 4mmx3mm package.
