IXYS Integrated Circuits Division (ICD), Inc., a wholly owned subsidiary of IXYS Corporation (NASDAQ:IXYS), announced the availability of the LIA135 and LIA136 low voltage optically isolated error amplifiers each with an integrated programmable precision shunt reference incorporated into a single 8-pin package. Unique to this pair of devices is the capability of the error amplifier and shunt reference to operate down to 1.6V, the industry’s lowest level, enabling higher efficiency, isolated low voltage power supply designs. The LIA135 and LIA136 offer a 1.299V internal precision voltage reference with a very low 0.5% tolerance for improved power supply accuracy.
