Summary
High Frequency 100mA CMOS Charge Pump, Inverter/Doubler Doc. No. MD-5003, Rev. L
Description
The CAT661 is a charge−pump voltage converter. It can invert a positive input voltage to a negative output. Only two external capacitors are needed. With a guaranteed 100 mA output current capability, the CAT661 can replace a switching regulator and its inductor. Lower EMI is achieved due to the absence of an inductor.
