Kinetic Technologies Announces Elevated Tablet Panel Power IC with 12-bit Gamma 2.2 Dimming for Next Generation High-Resolution and High-Refresh Rate Displays

KTZ8869: 8-Channel 40V Backlight Using I²C and PWM 12-bit LED Dimming Curve and 300mA LCD Bias Optimized for Advanced Panels

SAN JOSE, Calif., Dec. 17, 2025 /PRNewswire/ -- Power management and interface leader, Kinetic Technologies, is once again expanding its display power solutions portfolio with the introduction of KTZ8869. This device includes a next-generation highly efficient LED backlight driver with 8-channel current sinks and two 40V boost converters. It also encompasses an LCD bias driver with up to 300mA current which can drive next generation high resolution and high refresh rate LCDs.

LED backlight dimming is controlled with I²C or PWM inputs to provide linear or Gamma 2.2 profiles. The high switching frequency of the KTZ8869 allows the use of smaller inductors and capacitors, resulting in a simpler and smaller solution with fewer external components. The input operating range is from 2.7V to 5.5V, accommodating 1-cell lithium-ion batteries or a 5V supply. It integrates a full suite of protection features and a driver for an optional blocking MOSFET to isolate the boost converter output from the input during shutdown.

"Kinetic Technologies continues to expand its leadership position in display power products by introducing the KTZ8869. Gamma 2.2 provides a dimming curve well matched to the human eye yet expands the total range versus commonly used exponential dimming, allowing lower dimming for night-mode. A higher power 300mA LCD Bias converter was optimized for next generation high resolution tablets, including those with high refresh rates exceeding 120Hz. Higher LED brightness rated at up to 32.4mA is targeted at displays with High Brightness Mode (HBM) for increasingly demanding end use cases."

- Lu Chen, Senior Director, IC Analog Design at Kinetic Technologies

This front-running KTZ8869 driver provides engineers who are looking for a reduced footprint space in their next tablet or mid-sized display design a solution that integrates what previously were three ICs into one small chip. It is available in a RoHS and green compliant WQFN55-32L (5mm x 5mm, 32 Lead) tiny package. Powering 80 LEDs with its protection-rich, robust built-in features including inductor current limit protection, output short circuit protection, output over-voltage protection, LED fault (open or short) protection, optional disconnect switch and thermal shutdown protection.

KTZ8869 is available and shipping now. Visit Kinetic Technologies for more information.
