Step-up convertors raise voltages efficiently
The XC9128/29 series from Torex deliver efficiencies up to 93% over the entire load range, and can supply 500mA to a 3.3V load from a 1.8V battery supply.
They are particularly suited to improving the performance of VCXO modules and crystal oscillator circuits found in handheld and portable equipment such as mobile phones, PDAs and laptop computers.
The XC2300 and XC2301 are low power CMOS buffers with maximum operating frequencies of 70 and 160MHz, respectively.
Both are supplied in a compact mini-mold SOT-26 package.
The XC2300 is available with a choice of operating voltage: either 3.3V +/-10% or 5.0V +/-20%.
The XC2301 meanwhile is offered with an operating voltage of 3.3V +/-10%.
For both the XC2300 and XC2301 output is selectable from input frequency (fin) of: fin/1, fin/2, fin/4 and fin/8.
So, for example, from an input of 160MHz with the XC2301, typical output frequencies of 160MHz (fin/1), 80MHz (fin/2), 40MHz (fin/4) and 20MHz (fin/8) can be achieved.
For the XC2300 power consumption in stand-by mode is only 0.05mA, while that of the XC2300 is 4.50mA.
The devices are designed for tough conditions and can operate over a temperature range of -40 to +85C.
