FEATURES  
DESCRIPTION  
The TPS54227 is an adaptive on-time D-CAP2  
mode synchronous buck converter. TheTPS54227  
enables system designers to complete the suite of  
various end equipments power bus regulators with a  
cost effective, low component count, low standby  
current solution. The main control loop for the  
TPS54227 uses the D-CAP2mode control which  
provides a fast transient response with no external  
compensation components. The TPS54227 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 TPS54227 is available in the 8-pin DDA  
package, and designed to operate from 40°C to  
85°C.
