ADP3026中文资料High-Efficiency Notebook Computer Power Supply Controller数据手册ADI规格书

描述 Description

The ADP3026 is a highly efficient dual synchronous buck switching regulator controller optimized for converting the battery or adapter input into the system supply voltages required in notebook computers. The ADP3026 uses a dual-mode PWM/Power Saving Mode architecture to maintain efficiency over a wide load range.

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.
