High Efficiency, Low-Power Consumption  
D-Cap Mode Enables Fast Transient Response  
High Initial Reference Accuracy  
The TPS53124 is a dual, Adaptive on-time DCAP™  
mode synchronous controller. The part enables  
system designers to cost effectively complete the  
suite of digital TV power bus regulators with the  
absolute lowest external component count and lowest  
standby consumption. The main control loop for the  
TPS53124 uses the D-CAP™ mode that optimized  
for low ESR output capacitors such as POSCAP or  
SP-CAP promises fast transient response with no  
Low Output Ripple  
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  
Adaptive Gate Drivers with Integrated Boost  
Diode  
external compensation. 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.  
•
•
Internal 1.2-ms Voltage-Servo Soft Start  
Built-In 5-V Linear Regulator  
The TPS53124 is available in the 24-pin RGE  
package and in the 28-pin PW package and is  
specified from -40°C to 85°C ambient temperature  
range.
