New LCD bias power ICs from Nexperia deliver high performance in display devices

04.03. 2024 | News

Nexperia introduced a new series of space-saving, high-efficiency, dual-output LCD bias power supplies. These devices have been designed to 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.

The NEX10000 is an 80 mA dual output LCD bias power supply while the NEX10001 can deliver up to 220 mA of output current. 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 (more info).
