This reference design provides accurate measurements of ambient light intensity used to detect arc flash faults with a fast response of 1 ms: protecting or minimizing damages to power distribution switchgear. This design also monitors temperature (using switch: analog: digital or remote ): humidity: dust: and pressure accurately for online monitoring of busbar: transformers: and capacitor banks for early indication of faults: insulation failures: or ageing: resulting in increased operational life. This design provides a unique diagnostics approach within 1 ms during low load current for diagnostics of an ambient light sensor (ALS): increasing the system reliability. The sensors can be interfaced to microcontrollers with I2C or a low-power: wireless interface to perform weather transmitter functions for continuous online monitoring to simplify the system design.

This reference design generates an isolated 5V/100W output from a high voltage DC input. This design is intended to operate from the output of a PFC front end regulator. The UCC2897A is used to control an active clamp forward converter. Self-driven synchronous rectifiers allow for 91% efficiency.

This reference design provides accurate measurements of AC voltage and current inputs using a precision 16-bit SAR ADC over a wide input range: covering protection and measurement range (including sampling requirements of IEC 61850-9-2): simplifying system design and improving trip time performance and reliability. The analog input module (AIM) is isolated from the host processor using a digital isolator with an integrated power. For a limited function and cost optimized  design approach: An AC AIM can be designed using only three TI products: reducing system cost and board size. The alarm feature identifies the AC analog input faults on a sample basis for faster fault detection. The ADC has an additional auxiliary channel to diagnose the supply output of the digital isolator. A 12-bit ADS8668 ADC with a gain amplifier can increase the dynamic range by using programmable internal ranges: further optimizing the system cost.

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.
