LCD Bias Supply ICs

LCD Bias Supply ICs are multi-channel voltage converter ICs used to power the positive and negative bias supplies needed by LCD TFT panels. Discrete LCD Bias Supplies are used in Smartphones and Tablets with Full HD (FHD) or higher resolution panels. Utilizing a single boost converter and charge-pump technology, they provide multiple outputs with a single inductor; these products provide an extremely small and highly efficient programmable solution.
