FEATURES  
DESCRIPTION

D-CAP2™ Mode Enables Fast Transient  
Response  
The TPS54325 is an adaptive on-time D-CAP2™  
mode synchronous buck converter. The TPS54325  
enables system designers to complete the suite of  
various end equipment’s power bus regulators with a  
cost effective, low component count, low standby  
current solution. The main control loop for the  
TPS54325 uses the D-CAP2™ mode control which  
provides a very fast transient response with no  
external components. The TPS54325 also has a  
proprietary circuit that enables the device 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  
operates from 4.5-V to 18-V VCC input , and from  
2.0-V to 18-V VIN input power supply voltage. The  
output voltage can be programmed between 0.76 V  
and 5.5 V. The device also features an adjustable  
slow start time and a power good function. The  
TPS54325 is available in the 14 pin HTSSOP  
package, and designed to operate from –40 °C to 85  
°C.
