ZXLB1600 Datasheet (Zetex Semiconductors)

ZXLB1600, LCD BIAS BOOST CONVERTER

The ZXLB1600 DC/DC boost converter accepts an input voltage of between 1.6V and 5.5V and provides an adjustable output voltage of up to 28V for LCD backplane bias.

The device contains the output switch and a second switch to isolate the coil from the input and provide true isolation in shutdown mode
