Applications
LT1054IDWR is widely used in portable instruments and industrial equipment requiring a negative supply rail from a positive source, such as op-amp circuits, LCD bias supplies, and data acquisition systems. It also serves as a voltage doubler in low-power embedded designs where a charge pump solution is preferred over an inductor-based converter.
