Synchronous Buck Converter, Programmable Multiphase, with I2C Interface

Favorite

Overview

The ADP4000 is an integrated power control IC with an I2C interface. The ADP4000 can be programmed for 1-, 2-, 3-, 4-, 5- or 6-phase operation, allowing for the construction of up to six complementary buck switching stages. The ADP4000 supports PSI, which is a power state indicator and can be used to reduce number of operating phases at light loads. The ADP4000 includes an I2C interface, which can be used to program system set points such as voltage offset, load line, phase balance and output voltage. Key system performance data such as CPU current, CPU voltage, and power and fault conditions can also be read back over the serial bus from the ADP4000.
