FEATURES  
DESCRIPTION  
The TPS54427 is an adaptive on-time D-CAP2  
mode synchronous buck converter. The TPS54427  
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.

D-CAP2Mode Enables Fast Transient  
Response  
Low Output Ripple and Allows Ceramic Output  
Capacitor  
Wide VIN Input Voltage Range: 4.5 V to 18 V  
Output Voltage Range: 0.76 V to 7.0 V  
The main control loop for the TPS54427 uses the  
D-CAP2mode control which provides  
a fast  
Highly Efficient Integrated FETs Optimized  
for Lower Duty Cycle Applications  
70 m(High Side) and 53 m(Low Side)  
transient response with no external compensation  
components.  
The TPS54427 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.  
High Efficiency, Less Than 10 μA at Shutdown  
High Initial Bandgap Reference Accuracy  
Adjustable Soft Start  
Pre-Biased Soft Start  
650-kHz Switching Frequency (fSW  
)
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.  
Cycle By Cycle Over Current Limit  
APPLICATIONS  
The device also features an adjustable soft start time.  
Wide Range of Applications for Low Voltage  
System  
The TPS54427 is available in the 8-pin DDA  
package, and designed to operate from 40°C to  
85°C.
