Controller IC Chip - MOSFET RT6228CGQUF RT6228C K5= chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0891) 8A, 23V Synchronous Step-Down Converter with 3.3V/5V LDO The RT6228A/B/C is an advanced constant on-time (ACOTTM) mode synchronous buck converter. The main control loop of the RT6228A/B/C using an advanced constant on-time (ACOTTM) mode control which provides a very fast transient response. The RT6228A/B operates from 4.5V to 23V input voltage and the RT6228C operates from 5.1V to 23V. For the RT6228A, the output voltage can be programmed between 0.6V to 5.1V.  4.5V to 23V (RT6228A/B) and 5.1V to 23V (RT6228C) Input Voltage Range 8A Output Current  ACOTTM Mode Performs Fast Transient Response  ACOTTM Architecture to Enable All MLCC Output Capacitor Usage  Fixed 750kHz (RT6228C) and 500kHz (RT6228A/B) Switching Frequency  High Efficient Internal Power MOSFET Switch20mΩ (High-Side) and 10mΩ (Low-Side)  Adjustable Output Voltage from 0.6V to 5.1V (RT6228A)  Fi
