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
