RT5711A  
1.5A, 1MHz, 6V CMCOT Synchronous Step-Down Converter  
General Description  
Features  
Efficiency Up to 95%  
The RT5711A is a high efficiency synchronous  
step-down DC-DC converter. Its input voltage range is  
from 2.5V to 6V and provides an adjustable regulated  
output voltage from 0.6V to 3.4V while delivering up to  
1.5A of output current.  
RDSON 160mHS / 110mLS  
VIN Range 2.5V to 6V  
VREF 0.6V with 2% Accuracy  
CMCOTControl Loop Design for Best  
Transient Response, Robust Loop Stability with  
Low-ESR (MLCC) COUT  
The internal synchronous low on-resistance power  
switches increase efficiency and eliminate the need for  
an external Schottky diode. The Current Mode  
Constant-On-time (CMCOT) operation with internal  
compensation allows the transient response to be  
optimized over a wide range of loads and output  
capacitors.  
Fixed Soft-Start 1.2ms  
Cycle-by-Cycle Over-Current Protection  
Input Under-Voltage Lockout  
Output Under-Voltage Protection (UVP Hiccup)  
Thermal Shutdown Protection  
Power Saving at Light Load
