LCD bias power ICs extends battery life, video display lifetime

NEXPERIA NEX10000 80mA dual output LCD bias power supply and NEX10001 can deliver up to 220mA of output current series of space-saving, high-efficiency, dual-output LCD bias power supplies extend the lifetime of thin film transistor liquid crystal display (TFT-LCD) panels used in various applications including smartphones, tablets, virtual reality (VR) headsets, and LCD modules. Both devices feature I²C programmable asymmetric voltage outputs. The devices are internally compensated and require only a single inductor for both outputs, allowing for a small bill-of-material and pcb area. To minimize the amount of board area required in space-constrained applications, the NEX10000/1 are provided in a wafer level chip scale package (WLCSP) with 15 bumps and a 1.16 × 1.96 × 0.62 mm form factor, which is even smaller than standard wafer level packages.
