Description
- General Description:
- 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.
- Features:
- • Optional High-Frequency Operation Allows Use of Small Capacitors
- • Low Operating Current (FC = GND): -50 μA
- • 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 Outline (SOIC) Packages
