1.8A Step-Down Regulator with Differential Remote Sense in 2mm x 2mm WLP
General Description
The MAX8649 high-efficiency DC-to-DC step-down switching regulator delivers up to 1.8A of output current. The device operates from a 2.5V to 5.5V input voltage range, making it future proof for next-generation battery technologies. The output voltage is I2C programmable from 0.75V to 1.38V. Fully differential remote sense ensures precise DC regulation at the load. Total output error is less than 2% over load, line, and temperature. The MAX8649 operates at a 3.25MHz fixed frequency. The high operating frequency minimizes the size of external ponents. The switching frequency...
