EP7029B

Dual Output Integrated Voltage Regulator on Interpose

Introducing the World’s Smallest & Fastest Voltage Regulator

The EP7029 is a high-performance highly Integrated Voltage Regulator (IVR) with two outputs totaling 10A that enables the full integration of multiple voltage rails all in one IC, eliminating all external components.  Operating from a 1.8V input supply, the EP7029 offers the industry best density, efficiency, transient performance and dynamic voltage scaling (DVS) from any system input voltage.

Output Info

The two outputs are capable of 0.5V to 1.2V at 5A each to provide flat efficiency curves and ultra-wide bandwidth.

Programmability

The EP7029 offers extensive independent programmability for each of its outputs, requiring no external discrete components.  Highly accurate telemetry, diagnostics, warnings and protection as well as operating parameters such as output voltage, soft-start time and sequencing, DVS ramp speed, and phase shedding are all programmable via the I3C interface. The EP7029 reduces PCB power management area and components by 10x or more, reduces system power loss by 10-50%, and reduces power routing complexity on the PCB.
