General Description  
The TC1121 is a charge pump converter with 100mA  
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  
Temp.  
Range  
Number  
An on-board oscillator operates at a typical frequency  
of 10kHz (at V+ = 5V) when the frequency control input  
(FC) is connected to ground. The oscillator frequency  
increases to 200kHz when FC is connected to V+,  
allowing the use of smaller capacitors. Operation at  
sub-10kHz 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 10kHz is  
50µA, and falls to less than 1µA 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.
