Overview

This reference design showcases various power architectures for generating multiple voltage rails for an application processor module, requiring >1A load current and high efficiency . The required power supply is generated using 5-, 12- or 24-V DC input from the backplane. Power supplies are generated using DC-DC converters with an integrated FET and a power module with an integrated inductor for size. The design features a HotRod™ package type for applications requiring low EMI. It is also optimal for design time constrained applications. Additional features include DDR termination regulator, input supply OR-ing, voltage sequencing, eFuse for overload protection, and voltage and load current monitoring. This design can be used with a processor, digital signal processor and field-programmable gate array. It has been tested for radiated emission, per CISPR22 meeting class A and B requirements.

Features

Power supply generation with 24-V input using synchronous step down DC-DC converter with integrated FET, compact nano power module with excellent load transient performance and accurate output regulation
Power modules in QFN package that offer optimal thermal performance
DC-DC converters in HotRod™ package for low EMI
Power supply generation with 12-V input using OR-ing controller for redundant operation interfaced to high efficiency DC-DC converter or external evaluation module
Point of load (POL) supply generation with 5-V input using PMIC , DC-DC converter and linear regulators or DC-DC converter > 3A load with improved low load efficiency and load sharing
Clean supply using 1A, dual-output, low dropout linear regulator with low-noise, high-bandwidth PSRRR
