The TIDA-01369 reference design is a power supply designed for providing power to lock-step dual-core microcontrollers (MCUs) with functional safety architectures, regulating down from an automotive battery or industrial DC supply in a single stage. MCUs from multiple vendors are supported by the design. The core and I/O rails for the MCU are supervised; if a fault condition occurs, the MCU is disabled by hardware RESET output signals and the latching fault condition is reported to the MCU after normal operation is resumed. The reference design emphasizes the complementary features of three products from TI: the TPS653850-Q1 power management IC (PMIC), the TPS57160-Q1 asynchronous DC-DC buck converter, and the TPS3700-Q1 overvoltage and undervoltage supervisor.

The TIDA-01494 reference design is a compact, high efficiency, 24-V DC, 480-W nominal, 720-W peak output reference design for industrial AC/DC power supplies. The circuit consists of a front-end continuous conduction mode (CCM) power factor correction (PFC) circuit followed by a robust LLC stage with synchronous rectification. The design enables efficiency greater than 93.5% over a wide load range, allowing the system to work without forced cooling. The LLC stage, based on the UCC256301, takes advantage of the ZCS avoidance feature in the UC256301 to enable peak output power, minimizing the PFC Bulk capacitor for meeting holdup requirements, while making the system robust to short circuit and over current conditions. The UCC24612-2 based synchronous rectifier helps in minimizing the losses in the output rectifier, while its advanced proportional gate drive and dead time optimization features helps to avoid shoot through and minimizes losses.

This reference design is a 450W high-efficiency and super transient AC/DC converter for desktop PC PSUs, gaming PC PSUs, entry-level server PSUs, and other low-cost AC/DC PSUs. The circuit consists of a front-end continuous conduction mode (CCM) power factor correction (PFC) circuit, followed by an LLC-based second stage. The design uses the UCC28180 controller for the PFC stage and UCC256301 controller for the LLC stage to achieve a compact and robust control structure. Synchronous rectification based on the UCC24612 and low RDS(on) FETs aids in achieving higher efficiencies. This reference design can be used as an AC/DC supply in many applications demanding efficient and super transient power conversion.
