The TC1121 is a charge pump converter with 100 mA output current capability.

It converts a 2.4V to 5.5V input to a corresponding negative output voltage.

As with all charge pump converters, the TC1121 uses no inductors saving cost, size and EMI.

Optional High-Frequency Operation Allows Use of Small Capacitors.
Low Operating Current (FC = Open): - 50 A.
High Output Current (100 mA).
Converts a 2.4V to 5.5V Input Voltage to a Corresponding Negative Output Voltage (Inverter mode).
Uses Only 2 Capacitors; No Inductors Required.
Selectable Oscillator Frequency: - 10 kHz to 200 kHz.
Power-Saving Shutdown Input.
Available in 8-Pin MSOP, 8-Pin PDIP and 8-Pin Small Outlin.
