RichTek Technology Corporation Dc/dc Conv, Sync Buck, 1.2Mhz, Sop-8; Topology Richtek RT8293BHZSP

The RT8293B is a synchronous step-down DC/DC converter capable of delivering up to 3A output current with an input voltage range of 4.5V to 23V. It operates at a fixed frequency of 1.2MHz and features a current mode control architecture, which allows for optimized transient response across various loads and output capacitors. The device includes integrated N-MOSFET switches and offers adjustable output voltage from 0.8V to 15V, achieving efficiency levels of up to 95%. Key protective features include cycle-by-cycle overcurrent protection, input under voltage lockout, output under voltage protection, and thermal shutdown. The RT8293B also supports a low shutdown current of less than 3OºA, making it suitable for battery-powered applications. It is packaged in an SOP-8 (Exposed Pad) format, which aids in thermal management. This product is compliant with RoHS standards and is suitable for various applications, including wireless access points, set-top boxes, and industrial low power systems.
