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 connected to ground. 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  
NScurrent 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  
NSconnected OSC. Typical supply current at 10 kHz is  
50 μA, and falls to less than 1 μA 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.
