Enhanced step driver targets LED lighting market

Exar has developed an improved alternating current (AC) step driver for light emitting diode (LED) lighting applications. Combined with other iML offerings, the iML8684 provides a complete solution for LED light bulb and LED tube applications. Unlike conventional AC driver solutions which use a single large driver, iML has patented a unique distributed architecture of multiple small, low cost drivers.

5.5v over-voltage solution uses OPMs

Until now, portable devices supplied by USB, Li-ion or NiMH batteries with voltage levels up to 5.5 V could not use standard process devices, such as 3.3 V CMOS I/O transistors. This lead fabless semiconductor companies to use expensive alternatives, such as external regulators or expensive process options, including HV/BCD processes.
