The RT7279 is a high-performance, synchronous step-down DC-DC converter with internal power switches and synchronous rectifiers. It utilizes Advanced Constant On-Time (ACOT) control architecture to provide fast transient response and stable operation with ceramic output capacitors without requiring external compensation. The device operates from an input voltage range of 4.5V to 18V, delivers up to 2A of output current, and features a fixed 700kHz switching frequency. It includes cycle-by-cycle current limit, input under-voltage lockout, adjustable soft-start, and thermal shutdown protection.
