Product Brief AnD7122 (AnDAPT)

DrMOS Controller Buck LDO & LDSW PMIC Adaptable PMIC AnD7122
Product Description The AnD7122 Adaptable PMIC uses AnDAPT AmP™ advanced technology consisting of fully flexible digital fabric embedded with high performance analog blocks. The AnD7122 consists of one configurable DrMOS controller, one 10A high current synchronous Buck regulator, two high current LDOs, two Load Switches along with an integrated sequencer and four additional auxiliary LDOs. The AnD7122 is fully tested and ready for use in designs. The AnD7122 Buck regulators use voltage-mode control. The user can modify output voltages and rail sequencing using external resistors or WebAdapterTM online tool. The sequencer can be programmed based on either timed delays or Power Good (PGOOD) signals. Adaptable PMICs provide fastest prototyping and time-to-market, while providing best-in-class performance and flexibility. The Adaptable PMIC is optimized to power high-end processors by integrating multiple power rails into single- chip designs. Features Applications • One 40 A DrMOS Controller.
