company blog about Mingjiada Electronics Sells Texas Instruments TPS23730RMTR: High-Performance IEEE 802.3bt Type-3 PoE PD Controller

Mingjiada Electronics is currently offering the Texas Instruments TPS23730RMTR, a high-performance IEEE 802.3bt Type-3 PoE PD (Powered Device) controller.

TPS23730RMTR Product Overview
The TPS23730RMTR is a high-performance IEEE 802.3bt Type-3 1-6 class PoE 2 PD controller developed by Texas Instruments (TI), integrating an Ethernet Power over Ethernet (PoE) power device (PD) interface and an efficient DC-DC controller, suitable for flyback and active clamp forward (ACF) switch-mode regulator designs.

The TPS23730RMTR complies with the IEEE 802.3bt standard and supports power levels up to 60W, making it suitable for applications such as IP phones, wireless access points, and surveillance cameras.

TPS23730RMTR Product Features
Compliant with the latest standards: The TPS23730RMTR strictly adheres to the IEEE 802.3bt standard, ensuring compatibility with various PoE power supply devices (PSEs) compliant with this standard, enabling stable and reliable power transmission.
High Power Output: As a Type-3 PoE PD controller, the TPS23730RMTR can provide up to 60W of power output, meeting the high-power requirements of devices such as high-performance wireless access points, network cameras, and thin clients.
High-Efficiency DC-DC Controller: The built-in DC-DC controller in the TPS23730RMTR employs primary-side regulation (PSR) technology, using feedback from the auxiliary winding to control the output voltage. This eliminates the need for external shunt regulators and optocouplers, simplifying circuit design and improving efficiency. An optimised continuous conduction mode (CCM) control scheme works in conjunction with secondary-side synchronous rectification to further improve efficiency and load response performance.
Multiple protection features: The TPS23730RMTR includes over-temperature protection, over-voltage protection, under-voltage protection, and other protection features to effectively protect the device from damage caused by abnormal operating conditions, enhancing system reliability and stability.
Automatic classification and MPS functionality: The TPS23730RMTR can automatically negotiate with the PSE, adjusting its pulse current amplitude and duration based on the PSE type and system conditions to minimise power consumption while maintaining power supply, making it suitable for applications with low-power modes or multiple power supply configurations.
Rich Configuration Options: The TPS23730RMTR allows flexible setting of various parameters via external resistors, such as under-voltage lockout (UVLO), soft-start time, DC-DC controller slope compensation, and blanking time, enabling users to customise configurations according to specific application requirements.
