The LTC®3450 is a complete power converter solution forsmall thin film transistor (TFT) liquid crystal display (LCD)panels. The device operates from a single Lithium-Ion cell,2- to 3-cell alkaline input or any voltage source between1.5V and 4.6V.

The synchronous boost converter generates a low noise,high efficiency 5.1V, 10mA supply. Internal charge pumpsare used to generate 10V, 15V, and 5V, 10V or 15V.Output sequencing is controlled internally to insure properinitialization of the LCD panel.

A master shutdown input reduces quiescent current to<2µA and quickly discharges each output for rapid turn offof the LCD panel. The LTC3450 is offered in a low profile(0.8mm max), 3mm * 3mm 16-pin QFN package, mini-mizing the solution profile and footprint.
