Description
General part information
TPS23734 Series
The TPS23734 device combines a Power over Ethernet (PoE) powered device (PD) interface, and a current-mode DC-DC controller optimized for flyback and active clamp forward (ACF) switching regulator designs . In the case of flyback configuration, the use of primary-side regulation (PSR) is supported. The PoE interface supports the IEEE 802.3bt and IEEE 802.3at standard s for applications needing up to 25.5 W or less at PD input.
Programmable spread spectrum frequency dithering (SSFD) is provided to minimize the size and cost of EMI filter. Advanced Startup with adjustable soft-start helps to use minimal bias capacitor while simplifying converter startup and hiccup design, also ensuring that IEEE 802.3bt /at startup requirements are met.
The soft-stop feature minimizes stress on switching power FETs , allowing FET BOM cost reduction.
