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.

Package  
An on-board oscillator operates at a typical frequency  
of 10 kHz (at V+ = 5V) when the frequency control input  
(FC) is left open. The oscillator frequency increases to  
200 kHz when FC is connected to V+, allowing the use  
of smaller capacitors. Operation at sub-10 kHz  
frequencies results in lower quiescent current and is  
accomplished with the addition of an external capacitor  
from OSC (pin 7) to ground. The TC1121 also can be  
driven from an external clock connected OSC. Typical  
supply current at 10 kHz is 50 A, and falls to less than  
1 A when the shutdown input is brought low, whether  
the internal or an external clock is used. The TC1121 is  
available in 8-pin SOIC, MSOP and PDIP packages.
