6A, 23V Input Synchronous Original Step Down Regulator IC

Description The RT6306A is an advanced constant on-time (ACOTTM) mode synchronous buck converter. The main control loop of the RT6306A uses an advanced constant on-time (ACOTTM) mode control which provides a very fast transient response. The RT6306A operates from 4.5V to 23V input voltage, and the output voltage can be programmed between 0.6V to 5.1V. Features 4.5V to 23V Input Voltage Range 6A Output Current ACOTTM Mode Performs Fast Transient Response ACOTTM Architecture to Enable All MLCC Output Capacitor Usage Fixed 500kHz Switching Frequency High Efficient Internal Power MOSFET Switch- 30mΩ (High Side) and 15mΩ (Low Side) Adjustable Output Voltage from 0.6V to 5.1V Pre-biased Soft-Start Cycle-by-Cycle Over Current Protection Input Under-Voltage Lockout Thermal Shutdown Protection Output Over/Under Voltage Protection Ultrasonic Mode (USM)
