RT6226A/B/C  
6A, 23V Synchronous Step-Down Converter with 3.3V/5V LDO  
General Description  
Features  
4.5V to 23V (RT6226A/B) and 5.1V to 23V (RT6226C)  
Input Voltage Range 6A Output Current  
ACOTTM Mode Performs Fast Transient Response  
ACOTTM Architecture to Enable All MLCC Output  
Capacitor Usage  
The RT6226A/B/C is an advanced constant on-time  
(ACOTTM) mode synchronous buck converter. The main  
control loop of the RT6226A/B/C using an advanced  
constant on-time (ACOTTM) mode control which provides  
a very fast transient response. The RT6226A/B operates  
from 4.5V to 23V input voltage and the RT6226C operates  
from 5.1V to 23V. For the RT6226A, the output voltage  
can be programmed between 0.6V to 5.1V.  
Fixed 750kHz (RT6226C) and 500kHz (RT6226A/B)  
Switching Frequency  
High Efficient Internal Power MOSFET Switch-  
30mΩ (High-Side) and 15mΩ (Low-Side)  
Adjustable Output Voltage from 0.6V to 5.1V  
(RT6226A)  
Applications  
Industrial and Commercial Low Power Systems  
Fixed 3.3V (RT6226C) LDO Output Supplies 100mA  
Pre-biased Soft-Start  
Computer Peripherals  
LCDMonitors and TVs  
Cycle-by-Cycle Over-Current Protection  
Input Under-Voltage Lockout  
Green Electronics/Appliances  
Point of Load Regulation for High-Performance DSPs,  
FPGAs, and ASICs  
Thermal Shutdown Protection  
Output Over/Under-Voltage Protection  
Ultrasonic Mode (USM)
