This reference design is a high power PoE Powered Device (PD) plus active clamp forward converter. The TPS2373 high power PD controller EVM (TPS2373-4EVM-758) provides all functions necessary to implement an IEEE802.3bt-ready PD. This is paired up with an active clamp forward converter utilizing the UCC2897A controller. The high efficiency 24V/3A output using synchronous rectifiers is ideally suited for high power PoE applications such as IP security cameras and LED lighting applications.

The TIDA-01494 reference design is a compact, high-efficiency, 24V DC, 480W nominal, 720W peak output reference design for industrial AC/DC power supplies. The circuit includes a front-end continuous conduction mode (CCM) power factor correction (PFC) circuit, followed by a powerful LLC stage with synchronous rectification. The design ensures an efficiency greater than 93.5% over a wide load range, allowing the system to operate without forced cooling. The UCC256301-based LLC stage utilizes the ZCS avoidance feature in the UC256301 to achieve peak output power, minimizing the PFC bulk capacitor to meet holdup requirements while enabling the system to handle short circuit and overcurrent conditions. The UCC24612-2-based synchronous rectifier helps minimize losses in the output rectifier, while its advanced proportional gate driver and dead-time optimization help avoid breakdown and minimize losses.
The TIDA-00643 reference design is a 4.4 to 30 V brushless DC motor controller for high power propeller, fan and pump applications.

Low loss e-STARTER evaluation board based on ACST6 for compressor starter circuit
This reference design uses the TPS61088 to provide an envelope tracking power supply circuit for an audio power amplifier (PA). By adding the audio envelope signal to the FB pin, the output voltage of the TPS61088 can be varied according to the envelope of the audio signal. Therefore TPS61088 can provide dynamically changing power supply voltage to the PA. As a result, the PA maintains high efficiency over the entire output power range.
The PM2.5 infrared module uses infrared turbidity detection method to detect fine dust with particles > 1 μm. The PM2.5 laser module uses a stable airflow system such as a fan or blower, and uses an optical sensor to identify dust particles > 0.3 μm.
