TCM828  
TCM829  
Switched Capacitor Voltage Converters  
FEATURES  
GENERAL DESCRIPTION  
Charge Pump in 5-Pin SOT-23A Package  
>95% Voltage Conversion Efficiency  
Voltage Inversion and/or Doubling  
Low 50µA (TCM828) Quiescent Current  
Operates from +1.5V to +5.5V  
The TCM828/829 are CMOS “charge-pump” voltage  
converters in ultra-small 5-Pin SOT-23A packages. They  
invert and/or double an input voltage which can range from  
+1.5V to +5.5V. Conversion efficiency is typically >95%.  
Switchingfrequencyis12kHzfortheTCM828and35kHzfor  
the TCM829.  
Up to 25mA Output Current  
Only Two External Capacitors Required  
External component requirement is only two capacitors  
(3.3µF nominal) for standard voltage inverter applications.  
With a few additional components a positive doubler can  
also be built. All other circuitry, including control, oscillator,  
power MOSFETs are integrated on-chip. Supply current  
is 50µA (TCM828) and 115µA (TCM829).  
APPLICATIONS  
LCD Panel Bias  
Cellular Phones  
Pagers  
PDAs, Portable Dataloggers  
Battery-Powered Devices  
The TCM828 and TCM829 are available in a 5-Pin  
SOT-23A surface mount package.
