DESCRIPTION  
Wide Input Voltage Range:4.5 V to 24 V  
Output Voltage Range: 0.76 V to 5.5 V  
Low-Side RDS(ON) Loss-Less Current Sensing  
The TPS53125 is a dual, adaptive on-time D-CAP2™  
mode synchronous buck controller. The part enables  
system designers to cost effectively complete the  
suite of various end equipment's power bus  
regulators with a low external component count and  
low standby consumption. The main control loop for  
the TPS53125 uses the D-CAP2™ Mode topology  
which provides a very fast transient response with no  
external component.

Adjustable Soft Start  
Non-Sinking Pre-Biased Soft Start  
350-kHz Switching Frequency  
The TPS53125/7 also has a proprietary circuit that  
enables the device to adapt not only low equivalent  
series resistance (ESR) output capacitors such as  
POSCAP/SP-CAP, but also ceramic capacitor. The  
part provides a convenient and efficient operation  
with conversion voltages from 4.5 V to 24 V and  
output voltage from 0.76 V to 5.5 V.  
Cycle-by-Cycle Over-Current Limiting Control  
30-mV to 300-mV OCP Threshold Voltage  
Thermally Compensated OCP by 4000 ppm/°C  
at ITRIP  
The TPS53125 is available in the 24 pin RGE/PW  
package, and is specified from –40°C to 85°C  
ambient temperature range.
