DATASHEET ISL97682, ISL97683, ISL97684 FN7689 Rev.2.00 Compact 2-3-4-Ch LED Drivers with Phase Shift Control Sep 19, 2017 The ISL97682, ISL97683, ISL97684 are Intersils highly Features integrated 2-3-4-channel LED drivers that are suitable for ISL97682 - 2 x 100mA Channels medium size TFT-LCD backlights. These parts can drive multiple channels of LEDs from inputs as low as 4V to outputs ISL97683 - 3 x 50mA Channels of up to 45V. They can also operate from inputs as low as 3V to ISL97684 - 4 x 50mA Channels outputs of up to 26.5V in bootstrap configuration (see Figure Input Voltage 4.0V~26.5V with Max V of 45V 26 for 3V operation). OUT Input Voltage 3.0V (see Figure 26)~24V with Max V of 26.5V OUT The ISL97682, ISL97683, ISL97684 feature optional channels phase shift control. This feature is used to minimize the input, PWM Dimming Linearity output ripple characteristics and load transient, which help - PWM Dimming with Adjustable Dimming Frequency with eliminate or reduce the video and audio noise interference Duty Cycle Linear from 0.4% to 100% <30kHz from the backlight driver operation. - Direct PWM Dimming with Duty Cycle Linear from 0.009% to 100% at 200Hz The ISL97682, ISL97683, ISL97684 offer 8-bit PWM dimming for systems that need frequency tuning flexibility. With the Current Matching of 0.7% typical from 1%~100% Dimming unique adaptive boost switching architecture, the ISL97682, Selectable 600kHz or 1MHz Switching Frequency in PWM/PFM ISL97683, ISL97684 also offer Direct PWM dimming with Mode output, which follows input and achieves linearity as low as 0.009% at 200Hz or 1.35% at 30kHz. Dynamic Headroom Control The drivers incorporate dynamic headroom control that monitors Fault Protection the highest LED forward voltage string and uses its feedback -String Open/Short Circuit Protections, OVP, OTP signal for the minimum output regulation. The ISL97682, Thin and Compact TQFN-16 3mmx3mm Package ISL97683, ISL97684 incorporate extensive fault protection functions including string open and short circuit detections, OVP, Applications and OTP. The switching frequency can be selected at either 600kHz or 1.0MHz in PFM or PWM mode. These parts are Tablet to Notebook PC Displays LED Backlighting available in the thin and compact 16 Ld 3mmx3mm TQFN PMP LED Backlighting package and operate in ambient temperature from -40C to +85C.
