The MAX17243ETPA+ is a step-down (buck) switching regulator from Analog Devices/Maxim Integrated. It features a single output capable of delivering up to 3A of continuous current. The output voltage can be set to fixed 3.3V or 5V, or adjusted from 1V to 10V using external resistors. The device operates with an input voltage of 3.5V.
The regulator uses a synchronous rectifier topology for high efficiency, with a peak efficiency of 93%. The switching frequency is programmable from 220kHz to 2.2MHz, allowing optimization between efficiency and component size. The quiescent current is only 15µA in standby mode, and shutdown current is 5µA, making it suitable for battery-powered applications.
The device is available in a 20-TQFN (5x5) or 20-WQFN Exposed Pad package, both surface mount. It operates over a temperature range of -40°C to 85°C. Output voltage accuracy is ±2% for fixed outputs and ±1% for adjustable output.
