Analog Devices Inc./Maxim Integrated MAX8743ETX- is a highly integrated, dual-output, step-down DC-DC controller designed for high-performance power management applications. This buck regulator utilizes current-mode control with selectable switching frequencies ranging from 200kHz to 540kHz, allowing optimization for efficiency and component size. Key control features include adjustable current limit, enable functionality, on-time control for optimal transient response, and a power good output indicator. The device supports synchronous rectification for improved efficiency and is packaged in a 36-TQFN (6x6) for surface mounting. With an input voltage range of 2V to 28V, the MAX8743ETX- is suitable for demanding applications in computing, communications, and industrial sectors. The operating temperature range is -40°C to 85°C.
