FEATURES  
DESCRIPTION

D-CAP2™ Mode Enables Fast Transient  
Response  
The TPS54327 is an adaptive on-time D-CAP2™  
mode synchronous buck converter. TheTPS54327  
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  
TPS54327 uses the D-CAP2™ mode control which  
provides a fast transient response with no external  
compensation components. The TPS54327 also has  
a proprietary circuit that enables the device to adopt  
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 VIN input. The output  
voltage can be programmed between 0.76 V and 7 V.  
The device also features an adjustable soft start time.  
The TPS54327 is available in the 8-pin DDA  
package, and designed to operate from –40°C to  
85°C.  
Low Output Ripple and Allows Ceramic Output
