Renesas Electronics Corporation LED Drivers ISL97682IRTZ-TK

The ISL97682IRTZ-TK is a highly integrated LED driver designed for medium-sized TFT-LCD backlighting applications. It supports 2-channel output with a maximum current of 100mA per channel and operates from an input voltage range of 4V to 26.5V, with a maximum output voltage of 45V. The device features optional phase shift control to minimize input and output ripple, enhancing performance by reducing video and audio noise interference. This LED driver incorporates 8-bit PWM dimming capabilities, allowing for flexible frequency tuning and achieving linearity as low as 0.009% at 200Hz. It also includes dynamic headroom control, which optimizes output regulation based on the highest LED forward voltage string. Extensive fault protection features are integrated, including string open and short circuit detection, overvoltage protection (OVP), and overtemperature protection (OTP). The ISL97682IRTZ-TK is packaged in a compact 16-lead TQFN (3mm x 3mm) format and operates within an ambient temperature range of -40°C to +85°C.
