Internal Power Switch Buck
Linear Technology manufactures a broad line of high performance buck switching regulators with both synchronous and non-synchronous internal switches. These regulators offer typical input voltage capability from 2.25V up to 30V, switching frequencies up to 4MHz and high efficiency operation up to 96%. This combination of features allows very small circuit implementation and optimizes battery run time in battery operated handheld devices.
