RichTek Technology Corporation Dc-Dc Converter, Buck, 700Khz, Sop-8; Topology Richtek RT7281GSP

The Richtek RT7274/79/80/81 series is a synchronous step-down DC-DC converter designed for high efficiency and compact applications. It operates within an input voltage range of 4.5V to 18V and can deliver an output current of up to 2A. The device utilizes Advanced Constant On-Time (ACOT,Ñ¢) control, which enhances transient response and allows the use of low ESR ceramic capacitors for output stabilization. The converter maintains a constant switching frequency of 700kHz, ensuring efficient performance across varying loads. Key features include cycle-by-cycle current limiting for protection, adjustable output voltage from 0.765V to 8V, and integrated thermal shutdown. The device is suitable for applications in industrial and commercial low power systems, computer peripherals, and point of load regulation for high-performance DSPs, FPGAs, and ASICs. The product is RoHS compliant and halogen-free, making it a suitable choice for environmentally conscious designs.
