[SHINDENGEN ELECTRIC MFG. CO., LTD.]

The MD1320N is a non-isolated step-down DC to DC converter power IC with built-in main switch MOSFET and SBD flywheel. The maximum output is 7.5W (5V, 3.5A). The highly efficient power IC can be used over a wide range of applications. Furthermore, the output switching function permits optional selection of 3.3 and 5V.
The use of a surface mounted type SSOP-32 package permits controls with minimal externally mounted parts. As a result, the overall size of DC-DC converter power IC as a power supply unit is reduced and made as thin as possible.
