Package

The NDIP is a dual-in-line transfer mold package available in 26-lead version (NDIP-26L)

able to meet demanding cost and size requirements of consumer appliance inverters. It

consists of a copper lead frame with power stage and control stage soldered on it and

housed using the transfer molding process. The excellent thermal properties of the copper

allows good heat spread and heat transfer, furthermore, the thickness and the layout of the

lead frames has been optimized in order to further reduce the thermal resistance.

The package pinout has been designed in order to maximize the distance between the high

voltage and low voltage pins, by placing the relevant pins on the opposite side of the

package. This is mainly useful to keep a safe distance between high voltage and low voltage

pins and for an easy PCB layout.

Finally, thanks to the transfer molding technology and design optimization, the SLLIMM-

nano offers a high power density level in a very compact package while providing good

thermal propriety, electrical isolation and overall reliable performance.
