FEATURES  
DESCRIPTION  
The TPS54527 is an adaptive on-time D-CAP2™  
mode synchronous buck converter. The TPS54527  
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  
TPS54527 uses the D-CAP2™ mode control which  
provides a fast transient response with no external  
compensation components. The TPS54527 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 0.76V and 6V. The device  
also features an adjustable soft start time. The  
TPS54527 is available in the 8-pin DDA package,  
and designed to operate from –40°C to 85°C.
