KTZ8868 High Efficiency 8-CH LED Backlight Driver with Dual LCD Bias Power EVAL Kit Quick Start Guide
■Required Equipment
▲Bench Power Supply for VIN 5V and 3A, as needed for the intended application.
▲ Digital Multimeter – one or more, used to measure input/output voltages and currents.
●Quick Start Procedures
■Configure Kinetic I2C adapter output voltage jumper to 3.3V.
■Connect 5 Kinetic I2C adapter wires to evaluation board connector P1 (VDD_IO, HWEN, SDA, SCL, GND).
■Connect the other end of I2C adapter module to USB port on the computer.
■Connect one pair of banana-to-clip power cables to EVB test points at VIN and GND.
■Before connecting EVB to VIN bench supply, turn on supply and adjust voltage as close to 0V as possible. Turn off supply. While off, connect banana ends of Banana-to-clip power cables to VIN bench supply.
■Turn on VIN bench supply and ramp its voltage to 3.6V. While ramping VIN slowly, use bench supply’s output current indication to monitor the VIN current. If the current becomes high, reduce VIN voltage quickly to prevent damage. Inspect the setup for any wiring errors. Once VIN voltage settles to 3.6V, supply current should only be around a few μA since the KTZ8868 and KTC2115 devices are in shutdown mode.
