RT6226A/B/C
6A, 23V Synchronous Step-Down Converter with 3.3V/5V LDO
General Description
Features
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
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
