描述:
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 220 mA output current. The NEX10001 has excellent line transient and load transient responses.
