The RT7290A is a synchronous Buck converter with Advanced Constant On-Time (ACOT<sup>®</sup> ) mode control. The main control loop of the RT7290A uses an ACOT<sup>®</sup> 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. This IC also provides a 1.5ms internal soft-start function and an open-drain power good indicator.
