TC1121 Datasheet PDF - Microchip

●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
