TCM828/TCM829  
Switched Capacitor Voltage Converters  
Features  
Description  
• Charge Pump in 5-Pin SOT-23 Package  
• >95% Voltage Conversion Efficiency  
• Voltage Inversion and/or Doubling  
• Low 50 µA (TCM828) Quiescent Current  
• Operates from +1.5V to +5.5V  
The TCM828/TCM829 devices are CMOS “charge-  
pump” voltage converters in ultra-small, 5-Pin SOT-23  
packages. They invert and/or double an input voltage  
which can range from +1.5V to +5.5V. Conversion  
efficiency is typically >95%. Switching frequency is  
12 kHz for the TCM828, and 35 kHz for the TCM829.  
• Up to 25 mA Output Current  
External component requirement is only two capacitors  
(3.3 µF nominal) for standard voltage inverter  
applications. With a few additional components, a  
positive doubler can also be built. All other circuitry,  
including control, oscillator and power MOSFETs, are  
integrated on-chip. Supply current is 50 µA (TCM828)  
and 115 µA (TCM829).  
• Only Two External Capacitors Required  
Applications  
• LCD Panel Bias  
• Cellular Phones  
• Pagers  
The TCM828 and TCM829 devices are available in a  
5-Pin SOT-23 surface mount package.  
• PDAs, Portable Dataloggers  
• Battery-Powered Devices
