Mouser Now Shipping Nexperia NEX1000xUB Power Supply ICs for TFT-LCD Applications

by gabi

Mouser Electronics, Inc., the authorized global distributor with the newest electronic components and industrial automation products, is now shipping NEX1000xUB power supply ICs from Nexperia. These new, space-saving, programmable, high-efficiency, dual-output LCD bias power supplies are designed for space-constrained applications, extending battery life and video display lifetime for smartphones, tablets, virtual reality (VR) headsets, and LCD modules.

Nexperia’s NEX1000xUB power supply ICs, available from Mouser, combine an LDO regulator, an integrated boost converter, and a negative charge pump with an integrated active output discharge function to deliver programmable power supply efficiency in a wafer-level chip scale package (WLCSP), smaller than standard wafer level packages (1.16 mm × 1.96 mm × 0.62 mm, 0.4 mm pitch). The NEX1000xUB ICs feature I²C programmable asymmetric voltage outputs with programmable positive and negative output, from 80 mA dual output LCD bias (NEX10000UB) to 220 mA (NEX10001UB) output current.

NEX1000xUB ICs are internally compensated, requiring only a single inductor for both outputs. To address low power considerations in TFT-LCD applications that require longer battery life, the NEX1000xUB ICs have an internal boost converter which, depending on the load current, can operate either in continuous conduction mode (CCM) or pulse frequency modulation mode (PFM) to provide the highest level of efficiency. This feature reduces device current consumption, which helps to extend the life of single-cell Li-ion, Ni-Li and Li-polymer batteries from which they can operate. Both devices have an input voltage range of 2.7 V to 5.0 V and notably offer excellent line and load transient responses. These features reduce the amount of output ripple to provide more stable images, which can help extend the operating lifetime of an LCD display.
