DESCRIPTION
The MD1322F is a high-efficiency step down DC-DC converter power integrated circuit with main MOSFET switch and Schottky Barrier Diode. The MD1322F can deliver 7.5 watts maximum (5V, 3.0A) with high efficiency over a wide input voltage range. This device has output voltage digitally selectable from 2.5V to 12V. With the MD1322F you can construct a complete DC-DC converter
using only a few external components. Featuring an HSOP 28-pin surface mount package, the MD1322F allows you to incorporate a very small and thin power supply on your circuit board.
