The SR10000 Series is a SANYO's original SIP (System In Package) that includes a DC/DC converter control IC, a power MOSFET and a Schottky barrier diode. All these components are mounted into one thin-and-small package by utilizing SANYO's high-density mounting technology, "Integrated System in Board (ISB)". The advantage using this DC/DC converter package is that it greatly decreases its mounting area and space, compared with when the same circuit is set up with the discrete devices. In addition to that, it is very easy to assemble step-up switching power supply with by just adding voltage-setting resistance, inductor and capacitors.
