High-efficiency: low-emission: isolated DC/DC converter-based analog input module reference design
This reference design is a simplified architecture for generating an isolated power supply for isolated amplifiers for measuring isolated voltages and currents. A fully integrated DC/DC converter with reinforced isolation operating from a 5-V input with configurable 5-V or 5.4-V output (headroom for low dropout regulator (LDO)) generates the isolated power. Shunts that are interfaced to ±50-mV input range isolation amplifiers configured as channel isolated inputs measure the current. Potential divider output interfaced to ±250-mV or ±12-V input range isolation amplifiers configured as group isolated inputs measure the voltage. The outputs of the isolation amplifiers interface directly to 24-bit delta sigma analog-to-digital converter (ADC) or are scaled to ±10 V using gain amplifiers and interfaced to 16-bit SAR ADC for performance evaluation. On-board digital diagnostics improves reliability and enhances system performance.

High efficiency power supply architecture reference design for protection relay processor module
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.
