The PMP20795 reference design uses UCC256301 enhanced LLC controller with integrated driver to provide 24V/12A output from a nominal 380VDC input. UCC256301 provides hybrid hysteresis control (HHC) to enable a fast transient response. In this design, a 1st order system with over 6kHz bandwidth is achieved. In addition, the advanced burst mode allows this converter to achieve less than 200mW power consumption at no load. With 200kHz nominal switching frequency, the converter is able to achieve over 96% peak efficiency.

Continuous-Conduction-Mode (CCM) Totem-pole power factor correction (PFC) is a simple but efficient power converter. To achieve 99% efficiency, there are many design details that need to be taken into account. The PMP20873 reference design uses TI’s 600VGaN power stage, LMG3410, and TI’s UCD3138 digital controller. The design overview provides more details on the CCM Totem-Pole topology operation, gives the detail design considerations of the circuit, and provides magnetics and firmware control design considerations. This converter design operates at 100KHz. A soft start at AC line crossover minimizes current spike and lowers THD. The PFC Firmware measures AC current and PFC output voltage in real-time and predicts the dead time needed for the switch node to complete a full swing. The adaptive dead time control effectively minimizes both switching loss and GaN FET body diode conduction loss. A GUI is available to support parameter setting and control loop tuning.

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.

The HB-LLC isolated DC/DC stage is controlled by the UCC256301 hybrid hysteritic control LLC controller, which ensures fast transient response resulting in reduced PFC bulk and output capacitor dimension. Phase shedding in the PFC stage and the advance burst mode optimization feature in the LLC stage help in meeting high efficiency at 5% load (230V AC). The UCC24612 multi-mode synchronous rectifier controller realizes proportional gate drive, reducing the conduction losses in the output rectifier of the LLC stage, enabling high efficiency.

This reference design is to show two distinct ways to protect the TMDS lines of a HDMI 2.0 drivers and retimers from electrostatic discharge (ESD). The HDMI standard is used in many applications from set-topboxes to notebooks to TV's. Since these ports are almost always external they are susceptible to an ESD event. The high speed HDMI 2.0 signals mean that the drivers cannot integrate good ESD protection in the IC so a discrete ESD protection device is needed. The HDMI drivers are also generally extremely sensitive meaning the ESD protection has to be ultra-low clamping. This design will go through the initial HDMI 2.0 compliance data for two setups, the ESD testing done on each board and the final HDMI 2.0 compliance data after testing. For more information about protecting the other 5 pins on the HDMI connector please see the ESD Protection for HDMI Applications technote.
