RT7290A, RT7290AGQUF is Richtek ic with 3B= marking code, and is 6A, 23V, 500kHz, ACOT® Synchronous Buck Converter with LDO for System 3.3V. The RT7290A is a synchronous Buck converter with
Advanced Constant On-Time (ACOT® ) mode control. The main control loop of the RT7290A uses an ACOT® mode control which provides a very fast transient response with no external compensators. The RT7290A operates from 5V to 23V input voltage, provides a 3.3V LDO and a 300kHz CLK to drive an external charge pump. OCP, UVP and OVP are included in the RT7290A.
