The MIC2548-2YM is a miniature, linear, low voltage, low quiescent current, DC-DC step up regulator from Microchip. It is designed for boosting low voltage inputs in battery-powered, space-constrained applications. The device offers a wide input voltage range of 2.7 V to 5.5 V and adjustable output voltage of up to 7 V. The output current is limited to 1.0 A. The MIC2548-2YM also features current and temperature protection, soft-start, shutdown, PWM switching, and low ESR ceramic capacitors. The package size is tiny (1.5 mm x 1.5 mm) making it suitable for portable applications.
