Torex Semiconductor was established in Japan in 1995 as a CMOS analogue power management solutions specialist offering power management ICs that provide low current consumption, low operating voltage and ultra miniature packages. For the latest noise sensitive wireless applications, Torex have ultra low EMI Micro DC/DCs (with integrated inductor) and low noise LDO regulators.

For battery powered, power sensitive applications, Torex have solutions that consume as little as 0.5uA in operation and for more high voltage applications, Torex have 36V CMOS LDOs as well as 30V step-down switching regulators.

Voltage supervisors incorporating delay time, manual reset & watchdog functions.
