Torex Semiconductor, Ltd. is a manufacturer specializing in high-efficiency power supply ICs to meet future needs. The demand for compact lightweight, high-precision and low-cost power supply ICs is increasing every year. Low current-dissipating ICs are particularly needed to increase the degree of freedom in power supply design and permit more comfortabhle prolonged use of portable equipment. Making the best use of the advantages of analog circuit and CMOS technologies, Torex has developed products with a current dissipation of less than 1A, as well as products with ripple removal rate and operating speed improved to levels of bipolar ICs.

Moreover, Torex has developed the USP-6B package, enabling cutting-edge chip-size packages to be produced using existing production lines. The USP-6B, currently patent pending, is a breakthrough in that it reduces initial cost considerably and allows IC designs with any number of pins.

Major Products: Voltage Detectors, Voltage Regulators, DC/DC Converters, Temperature Sensors, Power MOSFETs, Schottky Barrier Diodes, and more.

Low-Supply Current, High-Speed LDO Regulators

TOREX announces a reduction in mounting area of about 44% (compared to previous Torex products) in the XC6501 series of low-supply current, high-speed LDO regulators which don’t need an output capacitor. Learn More...

Low Noise Amplifier for GPS

TOREX has become the first in the industry to develop a 1.6GHz LNA (low noise amplifier) for GPS using a CMOS process. Many existing LNA products use a GaAs or SiGe process. However, with the increasing demand for wireless devices in recent years, attention has begun to focus on CMOS process, a previously existing technology with a plentiful production capacity, as a process for LNAs. In quick response to this shift in focus, Torex has succeeded in bringing to market an LNA product for GPS that uses a CMOS process. Learn More...

2ch. Step-Up/Down DC/DC Controller with Manual Reset

Torex's XC9515 series consists of 2 channel synchronous step-down DC/DC converters and a voltage detector with delay circuit built-in. The DC/DC converter block incorporates a P-channel 0.35Ω (TYP.) driver transistor and a synchronous N-channel 0.35Ω (TYP.) switching transistor. By minimizing ON resistance of the built-in transistors, the XC9515 series can deliver highly efficient and a stable output current up to 800mA. With high switching frequencies of 1MHz, a choice of small inductor is possible. Learn More...
