The XC6190 series of push button reboot controllers, which are designed for system reboot by means of a signal input from external buttons, has been released by TOREX SEMICONDUCTOR. The timer reset ICs supply a reboot signal to the system when 'L' voltage is input into both the SW1 pin and the SW2 pin for the required time (reboot delay time) using two switches (physical buttons).

The XCL219/XCL220 module from Torex Semiconductor is designed to minimise unwanted radiated noise or EMI, making it suitable for sensitive RF applications. With its integrated coil, the XCL219/220 achieves a significant reduction in radiated noise across all frequency bands, when compared with a conventional DC/DC circuit with an external coil.

In A6.280 at electronica 2014, Torex Semiconductor will present the company's first PFM-only step-down DC/DC converter that has been specifically developed for ultra-low power applications. The XC9265 series consumes just 0.5µA during operation and is therefore suitable for applications that run from batteries for long periods of time.

Designed to prolong battery life in single-cell Li-ion battery applications where the output voltage is within the battery voltage range, the XC9306 converter has been released by Torex Semiconductor. When discharged, a Li-ion battery's operating voltage declines to the point that it can no longer power it's load. The synchronous buck-boost converter boosts the output voltage of the battery, extending it’s usable life.

Enabling designers to set the current limit to a desired value by using an external resistor, the XC8108/9 series from Torex Semiconductor provides an adjustable current limit feature. The device incorporates an 85mΩ P-channel MOSFET power switch for low ON resistance and is optimised for USB, power line and Hot plug applications.

Operating over an input range of 85-270V AC, the XC9401C is a highly efficient, step-down constant current controller for offline LED driver applications. Introduced by Torex Semiconductor, the driver employs a constant off-time control method which naturally reduces EMI and provides a stable power supply for LED lighting.

Torex Semiconductor has announced the XC9270/71 series step-down (buck) DC/DC converter with integrated 0.3Ω N-channel driver transistor that utilises a bootstrap configuration. Featuring an operating input voltage range of 7.0-30V, the devices withstand surge voltages of 46V for up to 400ms for more demanding Industrial applications.

Suitable for use with DC/DC converters and in low voltage applications, particularly in hand-held and portable equipment, the XBS104P11R-G, XBS304F11R-G and XBS306P11R-G Schottky barrier diodes have been announced by Torex Semiconductor. Schottky barrier diodes offer much lower forward voltage drop than standard switching diodes which means that they can offer high current capabilities, ultra fast switching and low power dissipation.

A power switch optimised for USB 2.0 and 3.0 applications, as well as power line distribution and Hot plug applications, has been launched by Torex. The XC8107 device incorporates 85mΩ Pch MOSFET power switch for low ON resistance.

With a built in adjustable watchdog timer, Torex Semiconductor's XC6130/31 voltage detector is suited for high reliability applications where the system needs to be able to recover from code errors without human intervention. The reset timeout and the watchdog timeout period can be adjusted using an external capacitor while a separate manual reset input on the XC6130 allows a simple push button interface.

Featuring an integrated coil to simplify board layout and minimise any unwanted radiated noise, the XCL101 series step-up micro DC/DC converter has been announced by Torex Semiconductor. Able to start operation from input voltages as low as 0.9V, the XCL101 is suitable for use with single alkaline or nickel metal hydride cells.

Torex have today unveiled a series of high speed transient response 1.5A synchronous step-down Micro DC/DC converters. Packaged in a small 2.5mm x 3.2mm x 1.0mm USP-9B01 package, the XCL213/214 series comes with an integrated inductor and requires only two capacitors connected externally to generate a stable power supply.  

Torex Semiconductor have today announced a new 1.5A synchronous step-down DC/DC converter featuring a new HiSAT-COT (Constant On Time) control method. The HiSAT-COT control method, featured in the XC9260/61 series, provides less fluctuation in oscillation frequency against load and input voltage when compared to standard COT control.

Torex Semiconductor have today announced a new step-down DC-DC converter with integrated 0.3Ω N-ch driver Transistor utilising a bootstrap configuration. The new XC9250 / XC9251 series feature an operating input voltage range of 7.0V to 30V and an operating temperature range of -40°C to +105°C. These features, coupled with the ability to withstand surge voltages of 46V for up to 400ms, make the new XC9250 / XC9251 series perfectly suite...

Torex Semiconductor have today introduced a new a step-down DC-DC controller IC designed specifically for applications that require high efficiency and low power consumption. The XC9252 operates from inputs up to 30V and requires only 30µA when operating in PFM mode under no load conditions. This helps meet the low power consumption demanded by an increasing number of applications.

Torex has developed the XCL213/XCL214 series of step-down "micro DC/DC" converters with integrated coil. The XCL213/XCL214 series is a new series of ultra-small (external dimensions: 2.5mm x 3.2mm x 1.0mm) step-down micro DC/DC converters with integrated coil that achieve a level of miniaturization and profile reduction that we believe puts these converters in the world's smallest class for a load current of 1.5A. 

Torex Semiconductor has today introduced a new series of synchronous step-down DC-DC converters. Featuring two integrated N-ch driver Transistors and a bootstrap configuration, the new XC9248 series has an input voltage range from 4.5V to 18V and the maximum output current is 2.2A. The XC9248 utilises a fixed PWM control method for high efficiency which also generates low levels of output ripple.
