TIDA-00500 Capacitor-Based Backup Power Supply for PLC Modules Reference Design | TI.com
TIDA-00500: TIDA-00500 is a reference design to provide power to load for short duration of time after a power interrupt has occurred. Traditionally Programmable Logic Controllers (PLCs) are equipped with a recharge battery source for alternative power. This battery source often suffers from drawbacks like complex charging topologies, charging time, periodic maintenance, and eco-hazards. In scenarios where PLCs need to be functional for a short duration of time after power interrupt, a capacitor based backup is a much simpler and more effective approach because of the higher power density in comparison to a standard battery-based solution.

Small Split Rail Isolated + - 5V Power Supply Generator
SMSPLITRAILISO-REF: A very low noise differential power supply for split rail systems requiring +5V and -5V (higher or lower voltage is possible). This design is fully isolated and capable of floating to over 500V differential from Vin to Vout (higher is possible). The LM5001 IC is a fully integrated flyback regulator which performs all of the current mode control for tight regulation and transient response. This design is a smaller version of RD-171. Design uses smaller components on only one side of a double sided FR4 PCB. This design provides low noise bias rails for ground referenced analog circuitry (under 2 mV p-p ripple noise up to 1 GHz). The design utilizes a very small size PCB footprint. This approach is ideal for many applications including low noise cable drivers, medical electronics, high fidelity low power audio, and other sensitive circuitry that can benefit from very low noise split rail biasing. Input to output isolation is employed for those applications where the input and output voltages might be at different potentials or when the input voltage travels across cabling which might pickup noise. The floating outputs avoid unwanted ground currents and the potential for additional noise pickup. For those that do not require isolation they can remove the feedback isolation section of the design and use a simple resistor divider for setting the feedback voltage.
PMP9487 CISPR 25 Class 5 Rated Multi-Output Power Supply for Automotive Cluster in Infotainment System | TI.com
PMP9487: PMP9487 is a conducted EMI optimized (CISPR 25) 8W SEPIC converter for wide range Vin automotive infotainment cluster applications using the LM5001 regulator IC (used as SEPIC), LM46002 (used as buck) and LM2831Y regulator IC (used as buck).
