The LM2575WT is a high efficiency step-up switching regulator manufactured by Microchip. It is a current-mode Buck-Boost converter that can provide up to 1.5A of output current. The device integrates the switch, controller and full power conversion circuitry, making it ideal for battery powered applications. The LM2575WT features an input voltage range of 2.5V to 24V, an output voltage range of 3V to 28V, and an output ripple of less than 3%. It also provides protection against input under-voltage, over-current, and over-temperature, with built-in soft start and adjustable output voltage. The device is packaged in a tiny 1.3 mm × 1.3 mm QFN package, making it an ideal choice for size- and cost-sensitive applications.
