AC/DC Control ICs

We have developed a lineup of products for a wide variety of fields, for applications ranging from small and medium power capacity PC adapters and LCD TV power supplies, to large power capacity servers and industrial power supplies.

High-side and Low-side Driver ICs

High-speed switching is possible for FET of various ratings through the use of the 3.3 V logic input.
Furthermore, the increasing of the negative voltage withstand capability secures higher reliability than other companies.

DC/DC Control ICs

A large number of applications can be supported with our wide-ranging product lineup that includes types with MOSFET built-n and not built-in, boost/step-down/reverse/fly back control, and 1ch-3ch output support.
