FEATURES  
DESCRIPTION  
The TPS54525 is an adaptive on-time D-CAP2™  
mode synchronous buck converter. The TPS54525  
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  
TPS54525 uses the D-CAP2™ mode control which  
provides a very fast transient response with no  
external compensation components. The TPS54525  
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 5.5 V. The device also features an adjustable  
soft start time and a power good function. The  
TPS54525 is available in the 14-pin HTSSOP  
package, and designed to operate from –40°C to  
85°C.
