The TPS23755 device combines a Power over Ethernet (PoE) powered device (PD) interface, a 150-V switching power FET, and a current-mode DC-DC controller optimized for flyback topology. The high level of integration along with primary side regulation (PSR), spread spectrum frequency dithering (SSFD), and advanced startup makes the TPS23755 an ideal solution for size-constrained applications. The PoE implementation supports the IEEE 802.3at standard as a 13-W, Type 1 PD.
The PSR feature of the DC-DC controller uses feedback from an auxiliary winding for control of the output voltage, eliminating the need for external shunt regulator and optocoupler. It is optimized for operation with secondary side diode rectifier (typically 12-V output or higher). Typically, the converter operates in continuous conduction mode (CCM) at a switching frequency of 250 kHz.
SFFD and slew rate control helps to minimize the size and cost of the EMI filter. Advanced Startup allows the use of minimal bias capacitor while simplifying converter startup and hiccup design.
Secondary auxiliary power detect capability provides priority for a secondary side power adapter, while ensuring smooth transition to and from PoE input power, with no efficiency or thermal trade-off.
The DC-DC controller features internal soft-start, slope compensation, and blanking. For non-isolated applications, the buck topology is also supported by the TPS23755.
