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.
