Fairchild Semiconductor International (South Portland, ME) introduced its new FAN5660, an inductorless, 100mA, dc/dc converter that has greater than 90 percent efficiency, making it suitable for portable and system voltage conversions.
Achieving over 90 percent efficiency at full load with a typical operating current of 120µA, the FAN5660 inverts a +1.5V to +5.5V input to a corresponding -1.5V to -5.5V output. The converter can split or double a full load of a power supply or battery, providing +2.25V in splitter mode and +9.5V in doubler mode. In a voltage-splitter mode it splits the input voltage in half, and in a voltage-doubler mode, it doubles the input voltage. Because the FAN5660 does not require an external diode in its voltage-doubler mode, it occupies less PCB area in designs. The FAN5660 is provided in a space-saving, eight-lead, SOIC package.
Pricing for the FAN5660 is $1.61 for 1,000-piece quantities. It is available now and delivery is eight weeks ARO.
