FEATURES  
The TPS23754/6 supports a number of input voltage  
2
•
Powers up to 30 W (input) PDs  
ORing options including highest voltage, external  
adapter preference, and PoE preference. These  
features allow the designer to determine which power  
source will carry the load under all conditions.  
•
DC/DC Control Optimized for Isolated  
Converters  
•
•
•
Supports High-efficiency Topologies  
Complete PoE Interface  
The PoE interface features the new extended  
hardware classification necessary for compatibility  
with high-power midspan power sourcing equipment  
(PSE) per IEEE 802.3at (draft). The detection  
signature pin can also be used to force power from  
the PoE source off. Classification can be  
programmed to any of the defined types with a single  
resistor.

Industry Standard PowerPAD™ TSSOP-20  
The dc/dc controller features two complementary gate  
drivers with programmable dead time. This simplifies  
design of active-clamp forward converters or  
optimized gate drive for highly-efficient flyback  
topologies. The second gate driver may be disabled if  
desired for single MOSFET topologies. The controller  
also features internal softstart, bootstrap startup  
source, current-mode compensation, 78% maximum  
duty cycle. A programmable and synchronizable  
oscillator allows design optimization for efficiency and  
eases use of the controller to upgrade existing power  
supply designs. Accurate programmable blanking,

DESCRIPTION  
with  
a
default period, simplifies the usual  
current-sense filter design trade-offs.  
The TPS23754/6 is a combined Power over Ethernet  
(PoE) powered device (PD) interface and  
current-mode dc/dc controller optimized specifically  
for isolated converters. The PoE interface supports  
the IEEE 802.3at (draft) standard.  
The TPS23754 has a 15 V converter startup while the  
TPS23756 has  
a 9 V converter startup. The  
TPS23754-1 replaces the PPD pin with a no-connect  
for increased pin spacing.
