The XC6502 Series of low dropout regulators from Torex Semiconductor provides an ultra low quiescent current of only 1.0µA. Available in industry standard SOT-23 and SOT-89 packages, these devices are particularly well-suited for power sensitive applications.

Torex Semiconductor has added to its dual LDO regulator line up with the introduction of the XC6416 and XC6419 Series. Available in an ultra small USP-6C package, which measures just 1.8mm x 2.0mm x 0.6mm, as well as the small SOT-26, these dual output devices meet the demands of battery-powered applications where small size and low power consumption are key design criteria. Typical applications include mobile phones, portable games, cameras, p...

The new XCM406 Series multi-chip module (MCM) from Torex Semiconductor combines two XC6210 high current, high speed LDO (low dropout) regulators in an ultra small USP-12B01 (2.8mm x 2.3mm x 0.6mm) package. With high performance, reliability and very low power consumption, these highly integrated devices meet the needs of battery-driven applications such as mobile phones, Bluetooth equipment, portable gaming devices and other portable equipment.

Many engineering students go through their degree courses receiving little clear advice about how to get the most out of their switching regulator designs. Torex Semiconductor has compiled a DC/DC Converters Study Guide, which will certainly help take the black art out of power circuit design.

Torex has unveiled the XC6501 Series of high-speed LDO voltage regulators. Featuring internal phase compensation, these devices ensure a stable output within a 1.2V to 5V range, without requiring a CL capacitor. The XC6501 is therefore an ideal choice for providing voltage regulation in space-constrained designs such as mobile phones, portable gaming devices and cameras.

Combining the XC6108 with the XC6109 voltage supervisor in one small SOT-25 package, the XCM410 Series is the newest multi-chip module from Torex Semiconductor and features an ultra-low power consumption of only 1.7µA. The supervisor IC is ideal for those applications that need to monitor more than one voltage rail with a high degree of accuracy, such as microprocessor re-set circuits, memory battery back-up switch circuits and power failure det...

The new XCM517 Series multi-chip module (MCM) from Torex Semiconductor combines two XC9235/XC9236 synchronous step-down DC/DC converters in a space saving ultra small USP-12B01 (2.8mm x 2.3mm x 0.6mm) package. These highly integrated devices are suitable for space conscious battery-driven applications, such as mobile phones, PDAs, digital cameras and other portable equipment.

Torex Semiconductor has introduced the XC25BS8 Series of PLL clock generator ICs with built-in crystal oscillator circuit, divider circuit and multiplier PLL circuit. Suitable for low voltage and battery-powered applications of between 2.5V and 5.5V, the devices can generate a high frequency output from an input as low as 8kHz by multiplying the input up to 4095 times.

Torex Semiconductor, the analogue power supply chip specialist, has introduced the XC6701 Series of 28V high speed low dropout voltage regulators. Ideally suited for 24V systems and industrial applications, these devices are available in a range of standard packages, such as the SOT-25, SOT-89, SOT-223 and TO-252, as well as the ultra-small USP-6C measuring just 1.8mm x 2.0mm x 0.6mm.

The new XC9128/XC9129 Series of synchronous step-up DC-DC converters from Torex Semiconductor allow engineers to achieve efficient step-up circuits from input voltages as low as 0.8V. These two series are suitable for a variety of battery-powered portable and hand-held device applications, such as digital audio players, digital still cameras and video equipment.

New from Torex Semiconductor is the XC6601, a 400mA high-speed voltage regulator with a built-in N-channel FET. With a dropout voltage of only 35mV at 100mA, the XC6601 is ideal for low dropout applications.
