GENERAL DESCRIPTION
The ADP3026 is a highly efficient dual synchronous buck switching regulator controller optimized for converting a battery or adapter input into multiple supply voltages. The ADP3026 provides accurate and reliable short-circuit protection using an internal current sense circuit, which reduces cost and increases overall efficiency. Other protection features include programmable soft start, UVLO, and integrated output undervoltage/overvoltage protection.
