Torex expands its low quiescent current inductor range

Inductors with a built-in, step-down DC/DC converter make up the XCL232 series from Torex Semiconductor. 

The synchronous step-down micro DC/DC converters integrate an inductor and a control IC in one tiny package. 

Torex claims that the efficiency performance at a light load current is dramatically improved by implementing low power consumption circuits which have 200nA consumption current, combined with the power factor modulation (PFM) control method. For this series of synchronous step-down micro DC/DC converters, efficiency at an output current up to 10 microA has been improved by 70 per cent or more compared to conventional products, claims the company. 

The XCL232 series is compatible with low consumption microcontrollers and SoCs, added Torex. In addition, a low output voltage from 0.5V can be selected, making it suitable for low voltage SoCs. 

The integration of a control IC and coil, it is possible to achieve compact, high efficiency from a light load and low EMI by simply attaching two small ceramic capacitors externally, said the company.

The XCL232 series are suitable for IoT, mobile and wearable devices where small size and high efficiency performance at a light load current are critical. They are also suitable for any devices that need to optimise battery life. 

Torex Semiconductor provides CMOS power management ICs for battery powered and energy efficient applications. It specialises in CMOS analogue technology, with LDO voltage regulators, voltage detectors and DC/DC converters making up its core product offering.
