DESCRIPTION  
Highly Efficient Integrated FETs Optimized for  
Low Duty Cycle Applications  
The TPS54295 is a dual, adaptive on-time D-CAP2™  
mode synchronous buck converter. The TPS54295  
enables system designers to complete the suite of  
various end equipments power bus regulators with a  
cost effective, low component count, and low standby  
current solution. The main control loops of the  
TPS54295 use the D-CAP2mode control which  
provides a very fast transient response with no  
external compensation components. The adaptive  
on-time control supports seamless transition between  
PWM mode at higher load conditions and  
Eco-modeoperation at light loads. Eco-mode™  
allows the TPS54295 to maintain high efficiency  
during lighter load conditions. The TPS54295 is able  
to adapt to both low equivalent series resistance  
(ESR) output capacitors such as POSCAP or  
SP-CAP, and ultra-low ESR, ceramic capacitors. The  
device provides convenient and efficient operation  
with input voltages from 4.5V to 18V.
