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.
