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 TPS53126 is  
a
dual, adaptive on-time,  
D-CAP2™ mode synchronous Buck controller. The  
TPS53126 enables system designers to complete the  
suite of various end equipment's power bus  
Adaptive Gate Drivers with Integrated Boost  
Diode  
regulators with  
a
cost effective, low external  
component count, and low standby current solution.  
The main control loop for the TPS53126 uses the  
D-CAP2™ mode control which provides a very fast  
transient response with no external components. The  
TPS53126 also has a proprietary circuit that enables  
the device to adapt to both low equivalent series  
resistance (ESR) output capacitors, such as  
POSCAP or SP-CAP, and ultra-low ESR ceramic  
capacitors. The device provides convenient and  
efficient operation with input voltages from 4.5 V to 24  
V and output voltages from 0.76 V to 5.5 V.

The TPS53126 is available in 4mm x 4mm 24 pin  
QFN (RGE) or 24 pin TSSOP (PW) packages and is  
specified from –40°C to 85°C ambient temperature  
range.
