A new two-cell supercapacitor charger has been launched that is designed to address problems in portable and data storage applications.

Linear Technology Corporation's LTC4425 tackles the peak power, data backup and 'dying gasp' needs in these types of device.

In order to do this, it employs a linear CC-CV architecture with thermal limiting, as this enables it to charge two supercapacitors "in series to a programmable output voltage from a Li-Ion/Polymer battery, a USB port, or other 2.7V to 5.5V current-limited supply" the firm explains.

The LTC4425 also works in two operating modes  normal and LDO  the second of which charges the tool to an externally programmed output voltage.

In addition, the device's onboard current-limited ideal diode means that it is suitable for use in a wide variety of battery and USB-powered equipment, like portable instruments and industrial PDAs.

Earlier this month, Yamaichi Electronics launched a new high-frequency connector that is perfect for use in audio systems, antennas and sensors.
