Fairchild introduces an inductorless, 100 mA DC/DC converter that is ideal for portable and system voltage conversions. Achieving over 90% efficiency at full load with a typical operating current of 120 μA, the FAN5660 uses two low cost capacitors, the charge-pump's 100 mA output replaces switching regulators, eliminating inductors. The FAN5660 inverts a +1.5 V to +5.5 V input to a corresponding – 1.5 V to – 5.5 V output. This converter can split or double a full load, +5.0 V input voltage, of a power supply or battery, providing +2.25 V in splitter mode and +9.5 V in doubler mode.
