260 mA dual output LCD bias power supply

The NEX10001 is a power supply IC providing programmable positive and negative output voltages for TFT-LCD panels. The device features an integrated boost converter, LDO regulator and a negative charge pump. The device requires only a single inductor allowing for a small Bill-Of-Material and the smallest PCB area.

The NEX10001 has an input voltage range of 2.7 V to 5 V and can operate from single-cell Li-ion, Ni-Li and Li-Polymer batteries. It can supply up to 260 mA output current. The NEX10001 has excellent line transient and load transient responses.

Interactive datasheet

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
