Power supply design features space-saving power IC: MC34700 power supply enables efficient control of four power rails and provides multiple output voltages for microprocessors, memory, and motors. Its IC is a 9 to 18 V quad-output integrated MOSFET device designed to reduce the complexity and streamline the development of power supplies. It is available in a 32-lead 5 x 5 mm QFN package, enabling the ability to generate up to four power rails in a small-footprint design. This capability reduces board space requirements over discrete designs. The wide input voltage range makes the device ideal for applications with a nominal 12 V supply. It has ample operating margin in systems where the 12 V supply is only 20% accurate. MC34700 is intended for applications with tight board space requirements and multiple power domains.
