Texas Instruments TPS75003RHLR | Demoboard TIDA-010011

Description

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.
