RT5712C  
2A, 1MHz, 6V CMCOT Synchronous Step-Down Converter  
General Description  
Features  
Efficiency Up to 95%  
RDSON 100mHS / 70mLS  
VIN Range 2.7V to 6V  
VREF 0.6V with 1.5% Accuracy  
The RT5712C is a high efficiency synchronous  
step-down DC-DC converter. Its input voltage range is  
from 2.7V to 6V and provides an adjustable regulated  
output voltage from 0.6V to 3.4V while delivering up to  
2A of output current.  
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  
Applications
