●Description
■The EP7143 is a high-performance highly Integrated Voltage Regulator (IVR) with four outputs of 3A each totaling 12A that enables the full integration of multiple voltage rails all in one IC, eliminating all external components. Operating from a 3.3V input supply, the EP7143 offers the industry best density, efficiency, transient performance, and dynamic voltage scaling (DVS) from any system input voltage.
■The multiple outputs are capable of 12A in total to provide flat efficiency curves and ultra-wide bandwidth.
■The EP7143 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, and DVS ramp speed are all programmable via the I2C interface. The EP7143 also features configurable IO logic levels through the VDDIO pin to support a range of 1.1V to 3.6V, and a pair of configurable GPIOs to support multiple user-defined features. The EP7143 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.
■Offered in a 5mm x 7mm x 0.75mm FcCSP package, the EP7143 is perfect for space constrained and thin profile applications. Die form is available.
