1. General description

NEX10001

2.7 V to 5 V

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.
