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.
