Power Management
Power management has evolved into the need to provide smaller, more precise, and more efficient control and distribution of power within portable devices. The batteries in these products need to be charged and managed carefully, and then have the power extracted from them in the most efficient possible manner. Switch cap voltage converters can create voltage levels greater than the battery as well as negative supplies, while LDO devices deliver low-noise supplies for audio and display functions.
