AnDAPT Adaptable PMIC

AnD8400
The AnD8400 consists of four configurable, high-output-current Synchronous Buck Regulators. The AnD8400 is fully tested and ready to use in designs. The AnD8400 Buck regulators use Voltage Mode methodology. The AnD8400 also has an integrated sequencer and 4 additional integrated fixed output LDOs.
AnDAPT Adaptable PMIC
Product Description
The AnD8400 Adaptable PMIC uses AnDAPT AmP™ advanced technology consisting of fully flexible digital fabric combined with
high performance analog blocks. The AnD8400 consists of four configurable, high-output-current Synchronous Buck Regulators. The AnD8400 is fully tested and ready to use in designs. The AnD8400 Buck regulators uses Voltage Mode methodology. The AnD8400 also has an integrated sequencer and 4 additional integrated fixed output LDOs. The user can modify output voltage and rail sequencing using either Configurator software tools. The sequencer has the capability to be based on timed delays or Power Good signals. Adaptable PMICs provide fastest prototyping and time to market, while providing best in class performance and flexibility. The AnD8400 design is available in the WebAmP™ software tool library for full customization capability. The Adaptable PMIC is optimized to power high end Processors by integrating multiple power rails into single chip designs.
