TPS23755RJJR Description

Short technical summary and product information.

The Texas Instruments TPS23755RJJR is an active component designed for Power over Ethernet (PoE) applications. It functions as an IEEE 802.3at Power Device (PD) and incorporates a no-opto flyback DC-DC controller. This device supports Type 1 (802.3af) PoE standards and can handle a PD power level of 13W.

 

Key electrical specifications include a maximum input voltage of 57V and a minimum input voltage of 10.2V. The PoE current limit is 405mA (min), and the inrush limit is typically 0.14A. It features integrated switching FETs with a low rDS(on) of 360mΩ (typ) and a robust 100V, 0.36Ω hotswap MOSFET. The controller also includes a 150V, 0.77Ω power MOSFET for the PWM controller.

 

Designed for flexibility, the TPS23755RJJR offers primary-side regulation, secondary-side adapter priority, and spread-spectrum frequency dithering for enhanced EMI reduction. It supports CCM operation and features advanced startup capabilities. The operating temperature range is -40°C to 125°C (TJ), making it suitable for various environmental conditions.

 

This component is supplied in a compact 24-VSON (6mm x 4mm) package with a surface mount type. It is ideal for designs requiring a complete IEEE 802.3at PD solution for type 1 PoE, offering Ethernet Alliance (EA) logo certified designs.
